I honestly don't know what any of that means. I use Bazzite for automatic updates, Gnome extensions, Portal/ujust commands, update rollbacks, and game mode/Gamescope. It's simply the most usable distro I've found. Bazaar is a nice bonus too. Gnome Software has infuriated me for a long time and I feel like a crazy person because no one talks about it.

I used Nobara for about a month and was constantly pestered with update notifications. There were multiple updaters, I didn't really understand how to use either of them, and they required a lot of manual input. Eventually I tried to do something else while the updater was running and broke it.
