Another vouch for EndeavourOS being Arch but with less hassle, I have installed and maintained for years both Arch and Gentoo and while I think those two are the best way to experience and learn Linux, I don't have as much time anymore, so I was trying out fedora for a while (left because some package lagged just a bit much for my preference; Emacs and some compilers/runtimes mainly) I wanted back into some cutting edge rolling-release distro.

I prefer Arch over debian testing and opensuse thumbleweed because of popularity and gaming, there is bigger chance that if a game has problems, these have been found out on arch especially with the steam deck technically increasing the user base of gamers on Arch.

EDIT: NixOS sound interesting because it might be even less time commitment to maintain I think(?), but the initial learning curve would be more time investment that EndeavourOS is since I'm very acquainted with how to upkeep and Arch system that I daily drive.
