I haven't played with it. However, I can say it is based on Fedora which is a good distro and Glorious Egg roll himself, besides working at Red Hat, is the creator of the Glorious Egg Roll version of the Proton compatibility layer.

Edit: stupid button, hit before I was finished. Besides the GE proton version, he does a lot of other enhancements to make Nobara more gamer friendly so it should be a relatively good distro to use because he knows the system better than most average Linux users and so provides the enhancements out of the box for gamers that want to game.

If you know what you are doing, the enhancements can be added to Fedora easily. But if you just want to setup and play immediately, Nobara is the way to go.
