Garuda is built for gaming and itās as beginner friendly as an arch based rolling release can be which is medium? It definitely isnāt super stable but I like it.
Iām not super knowledgeable about neon but I believe it can handle gaming fairly well. It looked to be much closer to the modern windows than any of the other distros Iāve seen.
I will recommend KDE as a desktop environment because you can easily change it.
I also hear good things about Pop OS which is a very beginner friendly distro thatās good for gaming but I donāt like GNOME and it doesnāt like my Dvorak
Nice, I've got a Steam deck already, but I haven't messed with it in desktop mode too much. I think I might start with the last 2 OS you mentioned and see how it goes. Thank you!
