To sum up, both of these cameras offer different megapixels and different sensor sizing. The G100 because of its tinier sensor will make shooting shallower DOF harder and the Sony A6400 will offer greater detail due to its extra 4MP. Higher resolution will also allow you to crop shots a little more aggressively. The fresher G100 will have an advantage when it comes to sensor tech.
