I’m on Garuda. For gaming, I think it’s an ideal option. It’s Arch based but comes with everything set up for gaming, and tools to install whatever you may need. I think it comes with the AUR set up automatically too (or it’s an option that’s easy at least), which isn’t necessary, but it does have some things you may want/need for modding and certain (very few) non-steam games. I think RuneLite for Runescape I got from the AUR, or something like that.

I haven’t tried Pop, and Fedora is alright though I personally didn’t care for it as much.
