I have found Mavericks to be pretty much rock solid. I've been using it since DP2 and even at that early stage, it was more stable and performed significantly better than the Mountain Lion GM.
Got a tip for us?

GM not ready for release

I too have found it to be rock solid. That said, I'm using a 15" rMPB. I'm not sure if people with older machines are necessarily going to have the same experience.
What can cause experience difference issues is how much people have tinkered with OS X in ways that aren't really a good idea. And what applications, especially ones with device drivers and/or kernel extensions they are using that need updates for Mavericks.
I also have the latest rMBP and I have been testing Mavericks since the first beta. The GM version is pretty stable but there are still issues with it. I would prefer if Apple solved the issues before releasing the product, but I am afraid this won't happen.
Im using a mid-2012 15" rMBP 2.3/16/256 Samsung Display with tons of hiccups and issues.
I have done 3 clean installs of the GM.

Yes, I'm sure people are having problems but, as stated by one of the commenters above, there are such wide variety of variables that can affect a particular individual's issues. The GM is not a public release as yet; many developers have not updated apps to make them compatible. Also the vast majority of people who have installed GM are probably not registered dev's i.e. to whom the GM has officially been released to. Who knows the legitimacy of the code they have installed or where they have procured it. Having said that, I would speculate there are just as many people on this board that are not facing issues vs those that are. Additionally, it's more likely for people to vent their frustrations publicly vs people just saying all is fine.
A little perspective.
What some people consider the best version of Mac OS X ever (Snow Leopard) had some MAJOR bugs on release.
The biggest one was that if the guest account was active, logging into it and logging out (including shutdowns and reboots) would wipe your own account. https://forums.macrumors.com/threads/801736/ It was fixed, but really should've been a showstopper for release.
Now does some slow scrolling seem like a major bug now?

It seemed rather buggy to me at first as well but it's my 3rd day using it now and everything seems fine. I am getting split second long beachballs every now and then and my volume feedback sounds are delayed but it works the same as ML except smoother and faster
I just tried to empty my deleted items folder using Mail.app and the app crashed...
Mail in generally has issues, especially with Exchange Server...
Been using the GM for 3 days now, has worked without a problem for me thus far, apart from some weird compatibility issues with some of my software
What software and what issues with them? This will help people who are trying to decide when to switch to Mavericks (after it is released).
I'm starting get the scrolling glitches people are talking about...I think
There is a subtle but apparent movement sometimes when you scroll down, like the page is jumping. It doesn't do it all the time but it's there
Another thing is when you are scrolling down a page, if you do it in short bursts instead of in one steady stream there is choppiness as you scroll. It's like they fixed the scrolling in one fashion but created another bug in the process. It doesn't seem to do it everywhere, but it's there.

Yea, I'm going back to ML again.
Safari is mainly the only thing that is buggy.
Today already I had to exit my macrumors tab twice after swiping left to go back a page, it just freezes. Safari itself is fine, just the tab is broken. Same thing happens sometimes when clicking the back button. That and pinch zooming will randomly stop working. Scrolling sometimes stops completely and I'm forced to use my mouse, when I scroll the wheel the bar at the right edge appears and I can drag it up and down.
Other than that scrolling is perfectly smooth, it just randomly stops completely sometimes.
Its a solid OS, but the GM does seem more buggy than the last DP, at least for me.
I'll probably wait till 10.9.1 before I buy it.

. Zero freezes so far doing that in mavericks, and I do a ton of web-browsing.
It's the latest version, for sure. Best? I'd stick with Snow Leopard if I could.
I concur. Been using Mavs since dp1. For the average user it's totally ready. Probably one of if not the best 10.X.0 release.

Mavericks and FCP X do not play well together.
My ProTranscoder Tool, and GPU Rendering keeps crashing, or ends up as Not Responding. So work is painfully slow in it.
Have to do one thing at a time, quit, relaunch and carry on to get things done.
Hoping the new version of FCP X plays nice with Mavericks, and does waste my time like it has so far. Over 5.5 hours to finish of a 20 minute video is a bad mmm'kay.

I'm not going to sit here and list all the bugs, but let me say there are many and they are rampant. I'll list a few here.
I use my 10.9 machine as my work machine, running a 2013 rMBP 15.
I work a lot with text editors, scrolling constantly fails even within basic apps such as textpad, then I need to use the arrows to scroll until scrolling magically works again.
Stability of the machine itself is pretty poor too. I've had quite a few kernel panics, and often when I put my machine into sleep I try and wake it up and it actually reboots.
So, lets talk about software compatibility. For those that work with virtual machines on VMware Fusion, forget about Mavericks. I am running the latest fusion package which is meant to be 10.9 compatible. VMs constantly shutting down, restarting, unity mode is basically a fail.
Granted it is not apples fault with regards to software compatibility, but it is something that needs to be considered, and it is the icing on the cake for an already unstable operating system.
For those of you who say "blah i've been running it for 3 days and its fine". I have been running mavericks on my work machine, every day since DP1.

I'd certainly notice if my scrolling was all glitched, I've had no scrolling issues in any apps. Thats not normal behavior and it certainly doesn't effect everyone.
You'd really think they'd make it GM if everyone had constant kernel panics too? There's gotta be something wrong on your system if thats happening..
100 percent agreed. My iMac wouldn't log in, icons disappeared, system lock ups. My Time machine backups pretty much got destroyed. Won't be updating until 10.9.1
I've done a fresh install, with nothing migrated. Also I had been running fine on ML. I probably get at least 1 KP every week.
I am using a magic mouse when the scrolling fails, if that helps / matters.
FWIW the trackpad seems fine. But I rarely use it unless at home or in meetings.
