Adjacently, Nobara is based on Fedora for gaming, uses KDE, and has a lot of packages pre-installed for a nicer end user experience. I used to use Kubuntu as my first foray into Linux desktop but I ran into a few issues. Nobara has been overall more stable and more reliable for my daily use.
I use a ps5 controller for all my gaming needs and it works great on Linux (Kubuntu/Nobara) and Steam Deck. I use hardwired when playing on my Linux desktop, but when playing on my Steam Deck it’s over Bluetooth while docked. Still works perfectly fine. I even played Crosscode with my controller just fine on both systems.
I primarily use it on my desktop for FFXIV which is why I do hardwired. Bluetooth can be squirrely if the game isn’t launched through Steam
