Listen, I love GIMP. I would never try to argue that the UI/UX is better than alternatives. There’s a reason it’s not the defacto tool to use in its industry, and it’s not the name.

That said, if you take the time to learn GIMP, it’s delightful. I personally like using GIMP more than, say, Photoshop, but I also learned photo manipulation on GIMP, and didn’t touch Photoshop until well after. GIMP’s UX leaves a lot to be desired for a newcomer to the software.

Endeavor is fantastic. For all the time I ran it, I never had any of the issues that people say Arch is riddled with: updates irreparably mucking up your system, packages making a mess of things, the AUR being unstable and dangerous. I’ve found that most of these claims come from people who are against the way Arch does things and have never actually tried it for any extensive amount of time.

You do need to be mindful of updates being pushed to your system (read the newsletters, they will tell you if anything in the update is broken and how to fix it) and have the technical know-how of how to fix those things when they do happen… And they will happen. That’s any rolling release, though.

Personally I use OpenSUSE Tumbleweed for gaming, it was a breeze to set up and continues to be a breeze to work with. I love every second of it. But EndeavorOS is a very close second for me.
