Unless you like your applications to save your window positions. I like Firefox to be on my left monitor, and if I use Wayland I have to manually drag it there every time I start it, because Wayland, in the year 2025, still lacks this basic feature that Windows, macOS, and X11 have had for like 40 years now.

(unless I use XWayland, which magically returns all of the missing functionality, though with a tendency to break other things)
