I haven't tried a full desktop environment that's not niri yet.
With the direction of KDE, I don't know if it would change things because the latest upcoming version will be Wayland with no X11 support[0]. It sounds like it would still support XWayland in the same way niri supports it too, but the potential root cause (Wayland based compositor) would still be there? I'd also be using the same NVIDIA drivers.
I'm not deep into the woods yet in Linux on the desktop so I'm speculating a lot here.
Certainly worth a test before I go crawling back to Windows tho, however 95% of the reason I switched is because of niri, it's that good. With that said if Plasma ends up working as well as Windows of course I'd still choose that over my old Windows 10 set up.
