Batman v.s. Superman

Ok who do you think would win an all out, no holds bar, no rules epic battle?
If it was punch for punch, I think we can all agree that Superman would win. However, what Batman lacks in superhero abilities he makes up for in brains. So I would think that Batman would have some kind if liquid kryptonite and inject Superman with it, leading of course to his demise.
Anyone elses' thoughts?
and p.s. Spiderman sucks balls
