Systemd was easy for me. All things worked in transition and have the big advantage that don't need shell scripts for create services. Wayland..., is slow, buggy, applications close without reason...
It was partially made for car infotainment systems that are knowingly weak hardware.
Nvidia's driver do something weird on Wayland when my laptop is connected to HDMI, probably something funky with the iGPU<->dGPU communication. Everything works, but at the whims of Nvidia an update reduces the maximum FPS I can achieve over HDMI to about 30-45fps. Jittery and painful, even on a monitor that supposedly supports VRR.
That's not really Wayland's fault of course, but in the same way Linux is broken because Photoshop doesn't work on it, Wayland is broken for many users because their desktop is weird on it.
