Water is sharp if you know how to do it. As far as water vs earth I believe Kishi is thinking that the earth absorbs the water into the ground. Sasori is the only person I know (before he died) that can the condense the water that it can cut a rock like it was nothing. Unless some other shinobi can do that then earth beats water.
