@pho4cexa for me it's the ability to remap keys
it used to be in firefox you could write an extension which would convert like, ctrl-n to down-arrow and ctrl-p to up arrow, etc, but now extensions are banned from doing that so if you hold down those keys you just get like ... twenty seven new windows or fifteen print dialog boxes or whatever
anyway my current xorg WM handles this brilliantly and moving to another system lacking that feature isn't really viable for me
I haven't spent enough time with wayland to know if there are other blockers for me because it only takes about 20 minutes of using the system without that feature for me to be ready to launch my laptop out the window
