Observations:

1) Catalina worked much cooler when I did a clean install and migrated.
2) Microsoft Edge is pretty performant, but I'd only recommend Chrome if you have a Google account.

Edge gets the job done but it performs better on Windows (which I guess is to be expected).

I have Brave as the default browser on my iPads and iPhones - I like it that much. I would use Firefox if it wasn't the webkit version of Firefox and if I could add the Ublock Origin. So overall, I don't use Safari.
 
I think that I've seen that. I use Firefox 98% of the time and will try Brave, then Safari, then Chrome if Firefox isn't working. I like Brave a lot better than Safari because of all of the add and tracking blocking that they do.
I used Microsoft edge on Mojave, mainly due to the ability to watch 4K on YouTube but the ad blocker I had (Wipr) didn’t work on there. Currently my Mac is getting its top case replaced so I haven’t had much time to experience Catalina, but I had a TM backup done in case I wanted to go back to mojave.
 
After some days, the MPB-13 of my son, stay on Mojave forever for the compatibility with 32 bits (Steam games), and the MBP-15 / iMac on Catalina. I like Catalina separate apps for the Music and Podcasts, and the Apple TV app has sense in a 27" display. I am in doubt update the iMac to BS, but if I go for it, firstly I will need to change the Fusion drive for a more speedy SSD.
 
My iMac 2017 is staying in Mojave. There’s too much to lose in the upgrading, for me:
- all 32bit apps, plug-ins... I use. Most of them are barely used, but I don’t see why should I trash them.
- “traditional” home drive structure. I have an internal ssd in APFS, but don’t dare going further. Backups, ext. boot drive, NAS TimeMachine... all works nicely.
- Native Windows install. (Catalina supported, but no BigSur, I think.
- ABOVE ALL: I know small problems appear, in all OSs. BUT problems in Mojave are well documented, and mostly resolved. It’s not the same just going up to Catalina, when new hiccups (per machine model sometimes) appear and there’s no clue. Just take a look at forums.
I feel safer in Mojave, and it does more (32bit) than newer OSs. And Catalina or Big Sur don’t bring any really new and important, and hardware efficiency seems similar.

I’m with you.

I use Mojave as my daily work OS, however I have installed Big Sur on a partition of the drive so I can play with it every once in a while and not feel like I’m missing out on anything.

That said, nothing in BS comes close to compelling me to abandon Mojave as my go-to OS.
 
I installed every single version of Catalina on an external SSD to try and I never found a compelling reason to upgrade.

I have moved my test SSD to Big Sur and it is far more stable than Crapalina was a year ago yet I still don't see an obvious justification to upgrade my main boot drive.

I will likely upgrade to Big Sur but it won't be until Q2 2021 at the earliest.

Crapalina isn't going to get any better. Like Mojave, it is now just getting security patches.

No matter what, I will likely upgrade to Big Sur by August 2021. I will always keep a Mojave boot drive for my Mac mini 2018 until I get rid of it.

with the new security update, i tried upgrading to Crapalina. Was only stable for a couple hours and BOOM! Usual High CPU usage, deleted daemon chewing CPU randomly every 5 second until reboot. Windowserver using way too much CPU from just playing movies and the list goes on.
Loaded my Mojave clone and cloned it back to the main drive that same night.
 
Perhaps I've said this before, but...
My 2018 Mini came with Mojave in March 2019.
Going on 2 years old now.

It will NEVER have the internal upgraded beyond Mojave. It will run Mojave until it fails. I have un-replaceable 32-bit software that I just want to keep using into the future.

The only piece of software in which I see potential problems is Safari, which Apple tends to "upgrade" with each OS revision until older versions of Safari won't load some sites any longer.

If that happens, I'll switch to a different browser as "my main browser".
(having said that, I still use El Capitan on my 2015 MacBook Pro, and that version of Safari is still working fine).

I do have Big Sur installed on an experimental EXTERNAL drive I plug in a boot from once-in-a-while. But again, I have no intentions now of EVER replacing Mojave on the internal drive...
 
I just installed TurboTax 2020 and it runs fine on Mojave but it showed me a popup stating that TurboTax 2021 will require at least Catalina. It is quite likely that I will have an M1X system by next December though; which would solve the macOS version issues for this one software product. I don't think that I have any other programs that won't continue to run on Mojave.

If Apple doesn't ship an M1X system by then (I find that hard to believe given the rumors that I've seen), then my options are:

  • Big Sur Virtual Machine (I've tried it and it's okay)
  • Windows 10 (I have two high-spec Windows systems)
I'd rather run it on an M1X system though.
 
I'm staying in Mojave mode till it finally dies or goes away for support..all my apps support it for now and I figure that Mojave will be around a few more years to work on my existing Video and Photography apps. Catalina from what I've read wasn't too good...sounds like it is the Window's ME for apple.

I have one system that I use daily on High Sierra and an old MacBook running Snow Leopard. Everything else is running Mojave. I like it and am quite happy with it. I have tried Big Sur and could use it but I see no reason to upgrade right now. I do have one piece of software that won't run on Mojave next year but I could just create a Big Sur Virtual Machine to run it there.
 
My primary iMac is still on Mojave and it's February. I feel no pressing need to upgrade it to Catalina; no apps I want to run require it, my system is fast and stable and I just can't be bothered.

Wondering if anyone else feels this way. This is the first MacOS release I'm feeling like skipping since I started using MacOS X in 2003. That's really saying something.

Luckily Apple is still supporting Mojave with security and Safari updates, but of course that won't be forever. Hopefully whatever comes out this year will feel more solid and refined and I'll be more willing to upgrade!

(Note that my work-issued 2015 Macbook Pro IS on Catalina, but I don't use it that much. So I HAVE used Catalina; I'm not "afraid of the unknown" or similar nonsense.)
I went to catalina

Catalina is shocking. Updated from mojave 10.14.6
Crash,crash and more crashes
Went back to Mojave and never get problems. I was running 64 bit apps and apple told me they were incompatible.ok im confused.are they telling me line 6,toontracks,positive grid,ableton are not going to work in catalina?
I was told these companies are not honest and do not make these compatible.they say they do but don't.so I asked apple this,why does logic x crash on catalina constantly?its ridiculous what they come out with.catalina has been out 15 months and its falls way behind mojave.if its not broken don't try and fix it comes to mind.

From what we seen on the Big Sur forum, I would not expect it to be better. I have updated a 5-year+ old MacBook Pro (mid-2014) to Catalina in order to be able to use TurboTax and perhaps other things next year, and have had problems with USB bridge and freezing up the two attached USB disks. This never happened with Mojave, so I am keeping my 'main' machine to Mojave and will have no choice but to use Big Sur if/when I get a new M1 mac this year. I have no plans to bring the MacBook back to Mojave as the USB disk freezing happens about once a week, and appears to indicate no S.M.A.R.T recorded errors.

In my case, it could be that a clean install could repair the USB issue but that is too distruptive for me and there is no guarantee it would solve the issue. I have never done a clean install but have upgraded only from the original 10.9.4 MacOS (Mavericks). I agree with the folks to think that MacOS updates should not be a step backwards and full/clean installs should not be required. Many of us choose Macs to not have to deal with these issues and one could userstand the 32-bit exclusion decision but not all the other regressions that we see being reported.
 
I have an old laptop that I won't upgrade to something newer than Mojave, just to be able to use legacy apps such as Adobe CS6.

My new to me 2018 i7 Mini runs Mojave and will til the end because not only is there 32 bit limitations, but I also require eGPU for those big projects that require it.

The way I see it, if I paid thousands in software and additional hardware, I'm going to run it for as long as possible. It really irks me that new yearly updates break so much older software that their old base depended on.
I mean we could run 68K applications into the new millennium with PPC G4/G5 Macs in Classic Environment. Sure it wasn't the best but it was possible.

Makes me kinda envy Windows users how they can just right click compatibility mode and be fine.

depending on your versions of those music apps it's possible that they're 32bit. Upgrading to Catalina is to be strongly avoided if you're using music software
 
I’ve been on Mojave since I bought my 2019 MBP. I use Pro Tools, which took forever to certify Catalina, and now I have no good reason to leave Mojave since things are pretty rock solid for me.

I’ll prob hang on till I have no choice. (Previously, I was on Yosemite for years.)
 
I'm probably going to skip Catalina. I've installed it on my MacBook Pro but not my primary machine.
There are still two 32-bit apps I need. One in particular and the developer has released a very buggy 64-bit version (EyeTV 4).
I used to update macOS's after the x.1 release but now wait until a year has passed so I'm always one version behind.
With official support for Mojave ending I'll have to upgrade eventually and it will most likely be Big Sur. I skipped Sierra as well.
Oh the days when you could count on a (fairly) stable macOS release! I miss Snow Leopard. (Not really, but you know what I mean.)
I'm also not happy with the switch from Intel either right now as I need to use some Windows apps with Parallels. I remember how the PowerPC to Intel transition went (with Rosetta) but the end result was Windows compatibility so all was good.

I'm torn on this issue now. The switch to Apple Silicon intrigued me enough that I bought a MacBook I didn't need, just out of interest. But my iMac is still on Mojave and I've no plans to change that. Mojave works so well and reliably, I can run a couple of Windows apps I have a morbid attachment to in Parallels, and there are some 32 bit Steam games I don't want to abandon even though I've not looked at them in years. But a delicious new iMac this year or next, that might tempt me, and in the end the refusenik always gets dragged along with the tide.

I'm just reaching the point of 2 years of ownership with my 2018 Mini.

It came with Mojave.
It's still running Mojave.
It will keep running Mojave into the future...

I'm staying with Mojave because of my older apps, experience no crashes and no surprises, so I don't need any extra hassles. The only machine that sees the internet often is my Mojave MB Air and since I'm an Edge browser user, it syncs perfectly with my Windows work PC and that's handy! What will make me upgrade would probably be a new MB Air with Apple Silicon in it and I would buy that if I no longer get updates with Edge under Mojave or my Air kicked the bucket. For security, I may entertain myself in paying for a premium subscription of MalwareBytes to protect my Air since Mojave will no longer receive security updates next year, though the free one works just fine as well.
