X is very bandwidth efficient, VNC is very latency efficient. X does try to be better on latency but a lot of the later toolkits aren't very good at avoiding the problem. There are smart X "compressors" (in fact much more than compression as they cache state and do other magic) such as NX which usually beat both X and VNC hands down.
