I know its not one of the three cameras you mentioned but we have the older version of this camera and love it.

The zoom is not that great but it takes great pictures, its waterproof to 10', and its really tough so you can just throw it in a backpack or a beach bag and not worry about it.
We have had ours for two years and had no problems at all.
