It's cute how people just all jumped on some weird Wayland love fest because X11 isn't "cool" enough for you. And it's mostly people new to Linux, gamers, ex-Windows.
X11 has been around for 4 decades. It's had rigorous development and evolution, is robust and reliable. But sure lets just throw it in the bin because...
It's going to take Wayland equally as long to be on par, these things don't happen overnight.
Remind me in 40 years time.
X11 is very old and all code has been glued on over the years. It is one big spaghetti mess. Very hard to work on and fix bugs. Wayland is much more modular and future proof.
