By default it uses KDE instead of GNOME, you have the choice though. It makes some stuff easier for new users. Bazzite is also optimized for gaming and in some areas tries to mimic the Steam Deck experience pretty closely. It also includes all the Universal Blue goodness like ujust (basically a collection of scripts that is very helpful for quickly installing and setting up various things on your system). It also includes some quality-of-life improvements in the Terminal. You could compare it to Nobara, but built on top of Fedora Atomic (Kinoite).
