All in all, each of the cameras come with different resolutions and different sensor dimensions. The GX9 because of its smaller sensor will make shooting shallower depth of field trickier and the Panasonic GX9 will show greater detail due to its extra 10 Megapixels. Higher resolution will also let you crop photographs a good deal more aggressively. The younger GX9 is going to have an edge when it comes to sensor tech.
