Linux

Xorg server is de-facto abandon ware. Most of the major (commercial) Linux distribution will switch sooner rather than later and they are taking their paid developers with them to work on Wayland. Xorg cannot muster enough interest to be able to push out regular releases, I think its pretty safe to assume noone will invest energy into support for new hardware at this stage either. The best you can hope fore is that security issues get patched somewhat timely.

So yeah, there's "no need to switch" because for most users, their distribution will make the choice for them within the next release or two.
