Canon Powershot vs Olympus XZ-1 in their underwater housings

Which is better for snorkeling photography in underwater housing

Canon Powershot S95 vs Olympus XZ-1 - features

Neither of these models (the XZ-1 or the S95) are the most recent in their respective ranges.

The Olympus XZ-1 has been superceded by the XZ-2.   This is a more expensive camera, largely due to the tilting touch screen.

Why pay more for features that you can't use in the underwater housing?   Of course, you may decide you want the XZ-2 screen for land use.

Canon has added the S100 and S110 to it's Powershot range.   The S110 is more expensive.
