Bazzite also has the backing of a bigger group of developers and community. Whereas Nobara is developed by a solo (kudos to him). But I would say Bazzite differs quite a bit too with its immutability, automatic updates, and thanks to libostree technology, after every update the previous version of the operating system is retained on your machine. This means, should an update cause any issues, you can select the previous image at boot. Additionally, it has support for gamescope, meaning Steam can boot straight into Big Screen mode, which is very handy for gaming pcs and steam decks etc… Can read the rest of the details over at bazzite.gg, if you’re not convince :P

I don’t know if its still the case but originally Nobara was a “this is for me but you can use it too” type of project.
