Oh my God! This one's REALLY difficult. Individually I would choose Mega Charizard X because of Tough Claws and Mega Charizard Y's low Defense, and Mega Charizard X's double resistance to Mega Charizard Y's Fire-type attacks. And I would choose Mega Mewtwo Y because of Speed, Sp. Defense and special attacks. As long as Mega Mewtwo X doesn't use physical moves, because Mega Mewtwo Y has a really low Defense and Mega Mewtwo X a really high Attack.

You know what? I'm joining Energy's team on this vote.
