I'm of the opposite opinion. Think twice before doing anything with X as the experience and knowledge you gain will soon be useless.
Instead invest in wayland, it works great and will only get better and X will only get worse at this point.
The pain points are few but yes, if you must have screen sharing with a particular app that doesn't work with wayland that might be a dealbreaker. If not, no reason to stay with X, pick a time when you are configuring a new computer or whenever it is a good time to make the switch and try it out.
