At the end of the day, Nobara is pretty much a one-man hobby project. Sure, there is a small community around it nowadays but even then, if the main developer decides to drop it, they’d have hard time keeping up. That’s why I’m usually hesitant to recommend these types of distributions and I’d rather recommend something tried and tested with a big community build over many years.

For me it’s pretty simple:
-older hardware/no need for up to date packages - Debian
-new hardware, needs up-to-date software - Arch
And that’s it. Though obviously, you can also use flatpak if you truly need newer versions of software. Personally I have arch on my gaming PC + Debian on my multimedia-consumption laptop.

It’s really weird how Mozilla is trying to market to the punk-anarchists and the AI techbros at the same time. It won’t work.
