Quite often, it can be tough to picture the difference between sensor dimensions purely by looking at technical specs. The picture underneath will provide you a more clear sense of the sensor dimensions in the WG-3 and Quattro.

As you can tell, both the cameras posses different megapixel count and different sensor dimensions. The WG-3 because of its tinier sensor is going to make getting shallower DOF more challenging and the Sigma Quattro will give you greater detail having its extra 13 Megapixels. Greater resolution will also help you crop photos somewhat more aggressively. The more aged WG-3 is going to be disadvantaged with regard to sensor tech.
