I've used both. My STRONG preference is for 1Password. It's amazing, and an absolute must-have Mac app.
Now, if you need something more cross-platform and less expensive, Last Pass is decent.
Thanks for the kind words! We hope you enjoy 1Password 4 as much as we have enjoyed making it!
Doesn't seem to be available yet for those of us who purchased earlier versions outside MAS.
I have family licenses for both Mac and Windows plus iOS and would love to be able to upgrade!

We have a few things to clean up for the website. We ran into a few issues trying to roll the site out last night so it was pushed to this morning so we could get a little sleep, it's going to be a very busy day

I do apologize for the trouble though. We'll get the website version up as soon as we can.
Interesting that it's out on the App Store before it's out on the Agilebits website.
See above, it'll be coming

Our developers are on it
Their
website says that they do have a special Upgrade price available, but it doesn't say what that price is.

Maybe they didn't put it up yet since they noted they were having issues hosting the app on their site.
Oh well... I can wait. Version 4 looks like a worthy upgrade.
Thanks for being willing to wait! We'll get the website store updated as soon as we can. We wanted to release the website version the same time we clicked the button for MAS release, but ran into a couple things that held back the website, and the MAS updated faster than we expected
Is this a free upgrade for those who already purchased? I have the Mac, Windows, and iOS Version, I really hope I don't have to pay (again) to upgrade each one!
All users who purchased from the Mac App Store get a free upgrade. We promised those users a free upgrade when we released on the Mac App Store.
All users who purchased from our website in 2013 will get a free upgrade. If you're on the cusp let us know and we'll work something out.
All users who purchased from our website before 2013 will get special upgrade pricing. It'll be up on the website as soon as we get it deployed.
The main feature for me that will keep me on 1Password is the availability of a Windows client. I need to be able to access my passwords from my Windows boxes/partitions too! Apple's support for Windows is diminishing, no more Safari, etc...
B
We have a big update to our Windows version coming too! Hopefully we'll have more to announce there in the coming months. Our Windows developer is anxious to see it in user's hands!
In my experience and as a user since beta, I have had to pay for every major update (1, 2, 3, etc).
Version 1 users got 2 for free. Version 1 and 2 users got special pricing on version 3.
We've only charged for 3 upgrades in our history:
* 1Password 2 for Mac -> 1Password 3 for Mac
* 1Password 3 for iOS -> 1Password 4 for iOS
* 1Password 3 for Mac -> 1Password 4 for Mac
In order

All previous users have gotten discounted pricing though.
I definitely had to pay for the 3->4 upgrade on iOS and the 2->3 upgrade on OS X.
However it seems that they are cutting MAS users some slack. Maybe because version 4 was already announced by the time 3 hit MAS.
B
Yup. That's exactly it. We promised it, we're delivering on that promise. Please enjoy 1Password 4!
I like having multiple URL's per login with this new version. So if for instance a banking site redirects to a different URL for logins 1Password now handles it seamlessly.
Great to hear you are enjoying this feature! I know there were a lot of requests for this in the past, so I hope that a lot of our users are happy for this feature
This looks like a good upgrade for an already great app.
Thanks so much for the kind words! I've posted this to our company chat room so the rest of the team can see.

Hope you don't mind!
I know only the MAS version will do iCloud syncing, but does (will?) the non-MAS version have any features that the MAS version does not have?
At this time, the only feature that the MAS version has over the website is iCloud syncing. I pushed hard for feature parity in this release because I wanted to avoid as much confusion as possible. We'll do everything we can to keep them in line and I'll fight hard for it
Just fired up the Mac App Store and the free upgrade to 4.0 was there. Just clicked Update and my 3.9.6 was upgraded in a few seconds
Boom!

Hope you enjoy it!
If I buy an upgrade from their site do I still get iCloud syncing or do I need to shell out the full price on MAS for this feature?
edit: From their FAQ: "To use iCloud syncing you should [read: need to] purchase on the Mac App Store."
Apple doesn't allow iCloud syncing with non-MAS apps. We wish we could include it though.
I have a PS3 and other devices that don't support 1Password. How are you 1Password users managing the non-supported devices, for example when buying stuff from PSN or Xbox stores? Passwords have become a pain in the ass lately so I'm really interested in starting to use 1Password.
I use diceware passwords for these types of things. There is some mention of it here:

They're long, strong and easier to type
Wow, really? I'm not seeing jack.
Anyone else having luck with the 'free upgrade' as can be seen.

Our website hasn't been updated yet. We've run into a few technical challenges, we'll get it updated as soon as we can. Sorry about that!
