Canon S120 vs Pentax WG-2

Let's look much closer at the Canon S120 and Pentax WG-2, one being a Small Sensor Compact and the latter is a Waterproof by companies Canon and Pentax. There is a significant difference between the resolutions of the S120 (12MP) and WG-2 (16MP) and the S120 (1/1.7") and WG-2 (1/2.3") provide different sensor sizing.

Factoring in size and weight, the portability rating of the S120 and WG-2 is 92 and 91 respectively.

Often, it is hard to picture the gap between sensor measurements purely by reading technical specs. The graphic here may offer you a more clear sense of the sensor measurements in the S120 and WG-2.

As you can tell, both the cameras come with different megapixel count and different sensor measurements. The S120 using its bigger sensor is going to make achieving shallower DOF simpler and the Pentax WG-2 will offer you more detail using its extra 4MP. Higher resolution can also let you crop photographs a good deal more aggressively. The fresher S120 should have an edge when it comes to sensor tech.
