6. Adaptability, Tactics, and Resourcefulness
Batman always has a contingency plan. Batman has been known to plan for the unlikely, hence why he carries around Kryptonite on his utility belt. An encounter between the world's finest wouldn't be a brawl, or a spontaneous fight, it'd be calculated to a tee. To think Batman hasn't already thought about how he'd tackle Superman, or how the fight would go is just naive. If Superman were to go rogue, corrupt or evil, Batman would be the first line of defense, and he'd certainly be prepared. Being his friend and companion for all these years only bears advantage for Bruce. He watched and observed Superman's fighting style down to the very movements, with his intelligence, psychological knowledge, and deep understanding of Superman's arsenal he'll be able to predict, dissect, and evade Clark's blows with ease. Superhuman brawn is only ideal if you can strike the foe which would be hard, considering in close quarters, Batman most likely has access to Kryptonite. With Superman's ideals, and optimistic nature he'd never expect the fight, or be prepared. With a powerful but limited skillset, Superman falls perfectly into a category of foe Batman should be able to dispatch.
