4. Bat-Vehicles, and Technology
As smart as Batman is, if it weren't for his technology, or his access to it, his chances would be pretty damn slim against Kal-El. You'd have to think a victory for Batman would involve some kind of gadget, or trick. Kryptonite Cannon? Bat-Suit? Anti-Super-Personnel Batmobile? Who knows. But Batman's sheer adaptability to adapt, is powered by his technology. It's in the very makeup of Batman, in his formula that he takes advantage of technology to adapt to any situation, threat, or problem. What resistance could Superman offer against technology designed to dampened his abilities? none. Sure, Superman knows Batman's skill set, and technique but as a fighter Superman isn't at all adaptive. He simply has what he has at his disposal, he wins with brute force, and bravado. Thus he's in no real position to react to anything Batman can through at him, he doesn't exactly have a plan B when it comes to combat. Punch, fly, heat ray, charge. If master Bruce Wayne can alter his technology to withstand the brunt of Kal-El's attacks, he should be the favourite to win.
