I like Wayland just because it lets me easily use two monitors of different resolutions and refresh rates.

I used X11 for about 6 months when I first used Linux because I still had an Nvidia GTX 1080 at the time and Wayland wouldn't even load for me then.

I did manage to get my monitor setup somewhat working on X11 through a lot of manual editing and the trade off constant screen tearing on my low hz 2nd monitor.

When I finally got an AMD card I loaded KDEs Wayland session on the same Linux install and it automatically set the max res and hz for both monitors including the new 1440p 170hz main monitor I got along with the GPU.
