Not quite. For starters, going by open bug reports and various forum comments, suspend and resume appear to be unreliable and buggy, especially with Proton - and based on developer reaction to at least one of the bug reports, there aren’t even any plans to fix this. This is an essential feature on a handheld gaming device, which means that this OS might not suitable for this device category at the moment.

Bazzite has potential, but it’s nowhere near as mature as Steam OS on the Steam Deck - and it might never be, because it’s meant to work on anything, lacking the close hardware-software relationship that Steam OS on the Deck has.

Also, since it’s using a different flavor of Linux as Steam OS as its foundation (Fedora vs. Arch), I would expect random games to not work or exhibit bugs that aren’t present on Steam OS. With Valve’s Steam Deck verified label, you can be reasonably certain that a game will work, but you can’t with other Linux distros. I’m basing this on reports on ProtonDB and from developers who have released games for popular distros, but then got notified of bugs that only appear on less common distros (read: not Ubuntu or Steam OS).

This doesn’t mean that you can’t have a great time with Bazzite. It might work just fine on your hardware, but there’s no guarantee this will be the case for everyone.
