All in all, both cameras have different megapixel count and different sensor sizing. The G100 because of its tinier sensor is going to make shooting shallow DOF trickier and the Panasonic G100 will resolve greater detail having its extra 14 Megapixels. Greater resolution can also allow you to crop pics a bit more aggressively. The fresher G100 should have an edge when it comes to sensor tech.
