I distro hopped to it from Bazzite a couple of months ago, and I could not be happier.
If you try the installer, be careful when selecting multiples DE/WM as the conflicts were not listed anywhere for the installation process.
Picking a single environment and then adding the others later was what worked for me.
I just used chaotic Nyx: https://www.nyx.chaotic.cx/ which is similar to Arch and Chaotic AUR so I REALLY wouldn’t suggest it unless you 100% know what you’re doing. Basically just set it up like you would any other thing with your flake.nix (if you use flakes that is)
