I use i3-wm. I know that there is Sway but it will require some effort to migrate. Also there are fresh reports that Wayland+Sway have problems with NVidia (even worse I have AMD + NVidia). I'd wait till it gets resolved or my current setup stops working.
The main issue is that X11 is an increasingly unmaintained case and all new development happens with Wayland anyway. So as long as you can deal with lack of support - I guess no need to move, but otherwise Wayland with KDE has been well usable for a while already.
