The GX8 featuring a larger sensor is going to make shooting shallower depth of field less difficult and the Panasonic GX8 will show greater detail having its extra 4MP. Greater resolution can also make it easier to crop images a little more aggressively. The newer GX8 should have an edge when it comes to sensor innovation.
