The future is now if you have Intel or AMD. Unfortunately NVIDIA users are lagging behind on that one. But that's fine, that's how stuff works. Even on Xorg land, when composition was first introduced, it was a mess. Most drivers didn't support it well, it was buggy. I think NVIDIA was the least bad one at the time. Eventually some DEs started switching on compositing on and people were annoyed because it didn't work for everyone. It was once one of the most common "help my graphics are weird since I updated". But those for whom it worked enjoyed their desktop effects and finally catching up graphically with Mac and OSX. And now unless you run XFCE or some other super lightweird DEs, you're using a compositor.

By all means keep using Xorg if it works better for you. That's why both are still going to be available for the foreseeable future. No big transition work by switching everyone overnight and everything goes flawlessly. People need to use it for important features that are missing to be found, and solutions to those to be found.
