I mean at the end of the day it’s all Linux so it’s not so different and just a minor convenience.
This is just for Fedora: comes with non-free audio/video codecs, non-free driver repos.
For other distro: It comes with nVidea drivers, WINE, OBS, Blender, Proton, Lutris, and Flatpak set up/preinstalled. (drivers detected on install I believe) there’s also package and kernel tweaks to boost gaming performance, supposedly.
In comparison to Mint: Fedora packages and kernel versions get updated a little faster than Ubuntu/Debian based distros.
So Nobara takes a lot of the “pain” out of system setup for people who are new to Linux and gamers/streamers.
I haven’t used it personally though I’m currently running EndeavorOS and using a SteamDeck for gaming.
