I am! I run it both on my gaming PC and laptop.

But it doesn't seem like a "typical" distro for a daily driver? How does Bazzite for example differ from Nobara which is another gaming-oriented distro?

Well, for starters, if you get the Bazzite-deck edition, your PC boots straight into Steam's game mode - in this mode, everything runs thru gamescope so you get all the awesome benefits like being able to use FSR even with games that don't support it, HDR and more. You get a console-like experience on PC, and it's awesome.

Another cool thing about this mode is that all your updates - including OS, Flatpak, firmware/BIOS, container, Nix, pip etc - all of it is presented as if it's a Steam update like in SteamOS - and it's automatic too, and it doesn't interrupt your gaming experience. Basically a unified update backend and frontend, which is awesome.

Compared to Fedora/Nobara, one advantage this has is that the updates are image based and atomic, so when you reboot, the new update goes live instantly so there's no wait-time. Another advantage is that your previous image is available in the GRUB menu, so in case the update broke something, you can always boot from the previous image - no need to even restore anything, no need to edit your fstab etc (unlike btrfs snapshot restores where the subvolid changes). And you can also pin "good" images to your GRUB menu (and I highly recommend doing that), so you can always fall back to a known good version. This came in handy on my laptop recently where after one of the Feb updates I was experiencing some weird graphics corruption in game mode, but thanks to image pinning I always had a working image to fall back to. Also, the rebase feature allows you to go back and forth between 90 days of images (stored on github), so it's easy to switch between various versions for testing. The rebase is also interesting because with just a single command you can switch between any other Fedora Atomic distro, so if you're bored of Bazzite or you want to try out a new DE, it's just one command to switch. And with pinning, you can always switch back instantly.

Finally, there's the whole immutability aspect. Personally I'm ambivalent on this, but the fact that it allows image/atomic updates (with easy rollbacks/rebases), I think of it more as a convenience - especially on a gaming-oriented machine, where I just wanna jump straight into my games without worrying about updates and broken systems.

So having used Fedora, Nobara, and finally Bazzite, I can highly recommend Bazzite as a daily driver - and it's 100% worth switching. AMA.
