That said, at least pre-52, I have to give pure fighting skills to guys like Richard Dragon, Lady Shiva, Bronze Tiger, Cassandra Cain, and (yes) Batman. These are the guys constantly referenced as the most skilled. As someone else already mentioned, Lady Shiva only seeks out the best to test her skills against and Richard Dragon even had to fake paralysis just to keep people from challenging him all the time. Cassandra Cain has been shown to match Shiva and Batman has mastered most any style the Earth has had to offer in an effort to be the best crimefighter in the world.
Do I think Batman's the most skilled fighter? No, I honestly think those four top him. But just the sheer volume of the skills he's picked up kinda ups his game a little bit more. On an even playing field where her powers were removed and he had none of his tools, I think it would be a tough battle, but in the end, I think he would edge her out.
