Ultimately it doesn't matter now, because Xorg is kind of in a state of "active abandonment", that is to say, the only maintenance being done is to ensure that no more bugs are being fixed aside from critical security issues on distros Red Hat still supports. In open source, you go where the developer energy is, and right now that's Wayland.

If you're about to tell me that XLibre is a viable alternative, no you're not because it isn't.
