Actually, I have survived Bowser's Super many times. It's easy to figure out and he becomes an easy kill for me. He's stupefyingly very slow and easy to avoid, and once he's back to normal, he's weak as hell. The Big Daddy's Super is good. The Enemy has a hard time moving and the Big Daddy will kill his foe in one hit. Best of all, it doesn't have any repercussions afterwards.

Also, what do you mean by Bowser is faster? I've seen them both move. Bowser is slower than Big Daddy and will be an easy target for Big Daddy's attacks.
