Which one(s) and why?
I’m probably going to stick with Arch, or maybe EndeavourOS.
I’ve hopped from distro to distro but I always keep coming back to Arch. The reason I use Arch is that it’s my weird sweet spot of “DIY” and “it just works”. It gives me a blank slate at first, but it lets me paint the canvas with whatever I want, however I want. It allows for some weird setups (like VFIO, for instance) and the wiki really helps with that. I don’t really use the AUR nowadays unless it’s for a package only available there, so I can’t say anything about that. I use Flatpak nowadays. Some people might prefer the AUR, that’s good for them! Right now it’s just not for me.
If I do distro-hop again, I’ll probably go for EndeavourOS just to have an Arch install that leans heavier on the “just works” side of things.
