IDK, but I would like to see Underdog and Mighty Mouse fight out.
I disagree ... because I think the comparison is flawed.
We don't know how smart Superman is ... nor how smart Batman is.
Batman is obviously more intelligent than the average human, to create all those "wonderful toys".
Superman doesn't need machines to beat most of his foes, but has created some that are just as advanced as Batman's.
Batman wins only by setting off a kryptonite nuke that destroys the entire planet. Otherwise Superman could start kicking Batman’s ****, fly to Venezuela for a drink. Run back and then vaporize Batman with his eyes.
PS. As a Batman fan, that was difficult to admit. But yeah...
