The thing is, Batman has more superpowers than any other superhero: The idiocy/incompetence of everyone around him to make him seem more intelligent/competent, (See anything involving the Riddler, where he's the only person in Gotham who can solve what are often some pretty simple riddles) increasing ability to avoid attacks based on how harmful they might be, (He'll get smacked by a thug with a baseball bat, but he will avoid bullets) he has a fortune that clearly stretches what a billionaire can afford, (You can't buy a supercar, a jet, a chopper, a spaceship, and an orbital space station without leaving a massive papertrail that will lead directly back to you) and the willing suspension of disbelief that enables fanboys to think he can stand a chance against a man who could cause an extinction event if he were so inclined.
Batman is more powerful than Superman, because while Superman is a god among men, Batman is a Mary Sue.
Superman is the story of a refugee who comes to embody the virtues of his adoptive home.
Batman is the story of a rich man spending countless amounts to beat up the poor when he could probably have spent that money on social programs and to buy the Gotham PD a BatComputer and body-armor.
