Aside from being based on Fedora 39 now, KDE is now the official desktop environment replacing GNOME. The reasons why are in the article.
The GNOME version of Nobara still exists, but it’s going to be the vanilla version shipped without any extensions (probably because many of them broke after moving to Fedora 39)
Honestly you should just stick to Fedora. If your looking for very user friendly then I would go for Linux mint.
Why?
Support and reliability
IDK , Nobara is really stable. The main difference for me was that it comes with all the AV codecs you could need, and a few tweaks for gaming. Saved me a lot of time in the end.
These are the reasons why I would consider installing Nobara over Fedora…
Yes. But Nobara is an experimental hacked-together distro.
It is not a Fedora project and thus has many flaws
Nobara is a cool project for testing stuff. But it lacks behind on Security a lot. Also the changes are maintained by basically a single person, so no it is not stable and you will not get good support.
Consider using Bazzite from ublue instead. This is an actually solid Distro, same modifications but very up to date and immutable. They also have way more versions targeted at various devices like the Steamdeck, the Ally, Razer, Surface, Framework etc.
