I will have to go with Batman.....He's a crazy bastard, with no real superhuman strength or powers, yet finds a way to beat the bad guys whom do have powers!!!!??? Now if you want to compare him to say....Superman (an *****), Spiderman (a Mutant), or punisher (a human who uses guns)...then I must say this...take away superman and spidermans powers, punishers guns, and batmans utility belt.....who would win a fight.....I believe it would be close between batman and punisher but batman would undoubtedly come out the victor! Any arguments?
