Arch. Bazzite/Nobara are for noobs (in a positive way, don’t get me wrong). Gaming is in spot where you want stability but also a rolling release, since we have daily improvements on essential packages; as an experienced user you can use Arch for that; consider also even Valve is on it with the Steam Deck (Arch-based).

umu, if I’m not mistaken, should be adopted in the future by all major gaming software like Lutris

What about the umu-launcher supported by GE?

I’m already a Syncthing fan but I haven’t found an Android app capable to rate tracks editing the tag.
