Well there's certainly one thing cap definitley has over bats looking at the directory link(thanks Venomfan via Spider-dan) is stamina given that his body doesnt produce lactic acid, which basically means his muscles will never ache so fatigue won't set in at all. Given that they are so evenly matched, and neither has an obvious edge, Cap would def win IMO because bats won't be able to take him down early and Caps slight edge in Strength,speed, agility and of course weight(240lbs to 210lbs is alot for two guys the same height and prob confirms caps strength advantage given they are both as strong as they can be for their size: it says cap can press 800lbs so bats can theoretically lift 120lbs less than that coz cap is 15% heavier than bats and 15% of 800 is 120 meaning bats can press 680lbs on a damn good day!This assuming they are as strong as they can be for their weight and I believe cap is stronger for his weight as well anyway). That clears up my opinion of who is a better athlete-the Captain! The edge in fighting skills needs to be far more than it is in Batman's favour to compensate for the disadvantage in size and strength and IMO it isn't.Bats is the best crimefighteradn detective the world has ever known and ever will know but he can't beat up Captain America
