Typically, it can be tough to envision the gap between sensor sizing only by looking at technical specs. The graphic below will offer you a stronger sense of the sensor sizing in the E-PL3 and Quattro.

As you can tell, both of the cameras feature different resolutions and different sensor sizing. The E-PL3 because of its tinier sensor will make getting shallow DOF more difficult and the Sigma Quattro will give more detail due to its extra 17MP. Higher resolution will also let you crop shots way more aggressively. The older E-PL3 is going to be behind with regard to sensor tech.
