Often, its hard to imagine the gap in sensor sizes simply by seeing technical specs. The picture below will help give you a better sense of the sensor sizes in the E-PL3 and ZS3.

As you can tell, the two cameras feature different resolutions and different sensor sizes. The E-PL3 having a bigger sensor is going to make shooting shallower DOF easier and the Olympus E-PL3 will provide greater detail having an extra 2 Megapixels. Higher resolution will enable you to crop photographs way more aggressively. The newer E-PL3 should have an edge in sensor innovation.
