Roy and Marth, they lack the long range offensive but make up with it with a slightly longer melee smash, I've had tons of times the length of my sword has hit the other players while keeping me out of their hitting range. The counter attack is also a great finisher i find for people coming back on the ledge, when they come in they might try to hit you and that sends them back, if they dont attack they will grab the ledge giving you time to recover from the failed counter.
