So far the Lifeproof gets my vote as the best for me. I absolutely love the overall design of the Otterbox, but the speakers are a big design issue. If they come up with a fix, it'll be a hit. Out of all of them I've tried, I felt the most protected with that one. Speakers and button response though, hats off to LP.
