It's more stable. But as I understand, it doesn't come with any proprietary drivers or blobs, so you've got to do an amount of tinkering and configuring to get it running for gaming. Especially if you've got Nvidia GPU.

Whereas with nobara or bazzite, those features are baked in already, by professionals.

You need them either way, so my question is, who do you trust more? Yourself? Or the developers behind the gaming oriented flavors of Fedora?

I went with Bluefin, based on silverblue, based on Fedora. It has all the gaming stuff I need, plus like bazzite, it's immutable (ish), so while it's harder to do some stuff the normal Linux way, it's also significantly more stable, because nothing I do or install ever touches the core operating system files. I can't break anything, and this makes me happy 😁

I mean, base Fedora probably is more stable.

Playing games requires an lot of extra stuff, and the kernal is more bleeding edge in nobara to keep those GPU updates (if AMD) and performance tweaks fresh and useful.

but generally speaking from my experience, Nobara is no more or less stable than anything else, windows or linux. And any issue I did rarely had was typically resolved with a reboot, and generally from a game.

Stability is a trap. It sounds automatically appealing but is so much more trouble it's worth for the benefits it provides, especially for a daily driver system intended for gaming, not a long-forgotten server running in a closet that's been doing the exact same thing for 20 years. The gaming ecosystem is not stable, new games are released constantly, new clients are released constantly, new updates and DLC are released constantly, new drivers are released constantly. You have no choice but to keep up and if your OS is not keeping up because it's "stable" you're in for a world of pain.

If you try to use a stable OS for an unstable goal you'll be fighting it all the time, ironically things will be broken far more often than any "unstable" equivalent, because you won't be able to get the latest rapid updates you need when you need them. To get things to work you'll have to force different updates into place one by one, piece by piece, then future updates will get broken because you'll end up with two copies of things that are conflicting one of which got manually installed.

Stable distros absolutely have their place, there's nothing wrong with them and they're typically the most used and popular distros because they are ridiculously good at doing what they're designed to do. But playing games on your desktop is not what they're designed to do.
