Both of them have issues depending on the setup. X11 has worked flawlessly in my experience. Wayland has worked the same for most.
Personally, Wayland still has some growing pains, especially in regards to Input handling (mouse, keyboard, etc). In X11 it was “trivial” to edit one file and have the settings stick across different WMs (switching from DWM to i3, etc.) There’s no standard for this with Wayland since it’s up to the compositor to handle these things, meaning you’re relearning how to do something as basic as setting pointer speed each time you try a new compositor. This is my only real fair gripe about it currently, as the rest of my complaints are just due to how young a lot of the Wayland-specific tools are - this will improve with time.
