It also depends on which incarnation of Aquaman we're talking about. If it's the first incarnation of Aquaman, then he's getting his ass kicked. If it's the second incarnation then yeah Superman might lose, of they're in the water. I say that because Aquaman has the crazy water hand in his second incarnation. I don't know much about New 52 though, I've stopped reading the comics recently.
