As has been mentioned before, even before gaining the mangekyo, hell before the cursed seal, Sasuke had exceptionally strong chakra for an uchiha. He also didn't suppress the kyuubi. He just told the mental projection in naruto to go away.
Also, they had numerous powerful members. It was noted that the clan had a history of killing friends to get the mangekyo after Madara and Izuna woke theirs. So, obviously, there had to be others but were killed for their eyes.
