It depends on the connection and the players you are playing with. If you play with european people on a Gold server or classic server then using UDP should be faster, since most servers are in the USA. UDP packets are sent directly to the other players, so you see the players with less lag and the other players see you with less lag, but peer-to-peer UDP is only working when both players are directly connected to the Internet or use a firewall/NAT which can forward UDP packets. Setting a fixed port for UDP often makes it easier to get the NAT forwarding it (you still need to configure it to use that port though).
