It should probably be "Waylands vs. X" since each of the Waylands supports different features and libraries to try to achieve the same ends. For example, some of the waylands use an external library, libei, to be able to support features like being able to share mouse/keyboard between computers. But some waylands, like sway, are actively hostile to libei and have made a point of never supporting it. So some waylands can share mouse/keyboard and some can't. There is no wayland. Just waylands.
