I use GNOME 43 on Debian 12. I sincerely enjoy it. The workspaces are intuitive, it looks and feels sexy, and it has a pretty great set of extensions. While I really appreciate other projects like KDE and XFCE, I think GNOME is probably the most mature DE I’ve used.
That said, I do have a few gripes. For starters, it’s pretty annoying that I have to use tweaks to access settings that should absolutely be included in the regular settings page. It’s also pretty dumb that I have to install an extension to be able to quarter tile. There are so e other small issues I have, but none more than I would have with any other desktop experience, and overall I adore what the devs have put together.
I was rocking a revived Thinkpad W540 which probably cost me around that price after I upgraded everything I could. The only word of caution I’ll give you if searching the used market is that older NVIDIA cards are deprecated by newer drivers on top of NVIDIA Optimus being a royal pain in the ass on Linux.
