Clearly, the 2 cameras have different megapixel count and different sensor sizing. The E-PL6 having a tinier sensor is going to make achieving shallower depth of field trickier and the Olympus E-PL6 will resolve extra detail having an extra 1 Megapixels. Higher resolution can also allow you to crop pictures a bit more aggressively. The more recent E-PL6 provides an edge when it comes to sensor technology.
