Not the original commenter, but Nobara is a great distro if gaming is your focus. It’s tweaked specifically for that purpose and has built up a strong community. I just hate that they use Discord for support.
Switching DEs can get messy in my experience with leftover packages and such. It’s best, in my opinion, to experiment in VMs and go from there, then go with a clean install when you make your choice. That’s what I did with KDE.
