I have never had any problems whatsoever with X. Switching to wayland for a couple days however and everything went to the gutter, text in in most application was pixelated, had to go against the wave because I have an nvidia GPU and had to install an unnecessary amount of other things just to be able to share my screen.
Ubuntu even tried to switch to wayland two times and had to revert their decision.
I'm not really sure how people in their right mind say wayland is good. Maybe I'm just doing something wrong here, but the experience of installing and forgetting is non existent with wayland, it feels like a clunky experimental wannabe X alternative.
Mind you, this was a couple months ago on arch Linux with sway.
