Plainly, both cameras have different megapixels and different sensor measurements. The GH3 because of its bigger sensor is going to make shooting shallow DOF easier and the Panasonic GH3 will render extra detail due to its extra 6 Megapixels. Higher resolution will also make it easier to crop shots a bit more aggressively. The newer GH3 provides an advantage in sensor tech.
