Ike isn't that good, but he's still is significantly better than Falcon. <<
And no, Roy is worse than Ike. Roy is pretty much never able to recover (like srsly, THE worst recovery in the game = autophail). Ike at least has OK recovery. Roy also has like...no kill options except for the F-smash. His damage output is also pretty lousy. This isn't nearly the case for Ike, who has been seen killing with everything. Also 16% Jab combo is win.
You could say Roy could combo, but that is because of Melee physics, and Brawl lacks combos so w/e. Besides Roy had like only one or two real ways of comboing. <<
And I hate Roy honestly. I've played FE6, so I can say that. Eliwood pwns Roy lolol.
