Hi, I was here and asked about a few distros already, so here's a quick summary of my situation:
I'm thinking about what distro to put onto my new Laptop, which will be used for University, Work, and just general daily usage. I am currently using EndeavourOS on my main PC and have been decently satisfied, but I want to experiment more. I've already asked if Arch was fine for this situation, to which the answer was a general "Yes, but keep x in mind" and I've asked about NixOS, where the answer was generally a no.
I've been looking around a bit more, and now I'm kind of curious about Fedora, specifically the KDE spin (or i3, I haven't quite decided). It seems to be cutting edge, compared to Arch's (and by extension EndeavourOS's) bleeding edge, and I'm wondering what you all think of it. From what I can gather it has basically all traits which people used to enjoy in Ubuntu, before Canonical dropped the ball on that. While it's not rolling release, the stability improvements and user experience compared to something like Arch, or even a more comfortable fork like EndeavourOS, seem quite decent, but in your experience, does that make up for the lack of the AUR and reduced applicability of the Arch Wiki?
I'm curious to hear about your experiences and recommendations!
Edit: I feel like I need to clarify, I know about the difference between EndeavourOS and Arch, I mostly just brought it up as a note that I am somewhat familiar with arch-based systems, and as a question of if it'd be stupid to just go with raw Arch, as EndeavourOS is basically the same, but with a more comfortable installer. I should have specified that more clearly in the first place, my apologies.
Use openSUSE Tumbleweed. It's a rolling release distribution with ~~the best~~ a great KDE Plasma implementation.
Now, your specific question boils down to choosing between Arch and Fedora, since, arguably, Endeavour OS is actually Arch Linux. Now, as you're willing to use a Qt-based DE, specifically Plasma, I'd say none of your options are ideal. That's why I mentioned openSUSE Tumbleweed, but, for you, I'd say Arch Linux, however, you currently use Arch Linux, hence, you should just switch to the Plasma DE.
Opensuse, just as
has GNOME as their primary Desktop. I would not say "has the best KDE implementation" for any of those.
