I use Fedora 38, it’s stable, things just work, and the software is up-to-date.
OpenSUSE Tumbleweed. I like it for being a rolling release with quality control. On the one hand I don’t like its restrictive defaults but on the other hand I know enough to work with them and that’s given me a leaner system.
That’s also what I run.
I want a boring up to date system with a good KDE desktop that just works (even with an nVidia GPU). Tumbleweed is fine. I don’t want to mess with my computer, I want to use it. I messed with it ages ago when I had to enter xmodelines by hand to make the damn thing work, I’m glad we’re past that.
