I would recommend looking at Fedora for your next step in distro surfing. Fedora stays close to the bleeding edge without going full yeet over the edge. Fedora offers Gnome and KDE as the "standard" choices for your desktop and a good number of spins to look at also. Plus there are the Atomic versions as well.
One of the spins is the COSMIC DE, and I'm running it on a mini desktop. It's OK, but I agree with you, it's not quite finished yet. When Fedora 44 gets released, I think I will go back to LXQT on that box. I just rebased my Kinonite laptop to Aurora 44 Beta for fun.
