As you have seen, each of the cameras come with different megapixel count and different sensor dimensions. The RX100 IV because of its larger sensor will make shooting shallower depth of field less difficult and the Sony RX100 IV will provide extra detail as a result of its extra 6 Megapixels. Greater resolution can also allow you to crop pics a good deal more aggressively. The more recent RX100 IV will have an advantage when it comes to sensor tech.
