Dedicated servers mean that they aren't player hosted. P2P servers select the player with the best connection and ping off him therefore giving that person an advantage. Ever been kicked out of a lobby in COD or see that host migration prompt? That means the host left the server. Dedicated servers do not have this issue and the only time someone has an advantage is if they have a better internet connection. This time everyone is on a level playing field and if you're ping isn't as good as others it is your fault.
COD:Ghosts on Xbox using dedicated servers is huge.
