One thing I really like about Bazzite (compared to EndeavourOS which I ran before), is that it just works for gaming. Lots of little tweaks and stuff to get certain qol things working in EOS, are just installed and configured by default in Bazzite.
The stability is super impressive... I used to rely on TimeShift on EOS to roll back when I broke shit (which was over and over, because that's how I learn), and while it's trivial to rollback on Bazzite, I've never even been close to needing to. It's just hard to break (and if you do, just reboot it and everything is fine).
It's definitely more user friendly, but I wouldn't say immutable like Bazzite is only for non-tech people.
