I totally concure with Sneek. Nightwing is the obvious champion of this fight.

Daredevil might be the Man without Fear in the Marvel Universe, but Nightwing has the man without fear in nearly all comic universes since he was born.
Dick was raised from birth to be a skilled acrobate. He literally learned to walk on a tight-rope. That already shows he's a better acrobat than Matt.
He's one of the top 10 fighters in the DCU, he's an expert detective only under Batman, he's a natural leader and tactician, and lets be honest, he's taken down stronger people than Daredevil when he was 10 years old.
Daredevil's primary trick is his sonar hearing and Nightwing can easily get around that with one of his bat-gadgets.
This is absolutely no contest.
BTW: Someone voted over in the Bat vs. Cap contest Marx. Batman won.
