As you have seen, both of these cameras offer different megapixels and different sensor dimensions. The A7S III with its larger sensor is going to make shooting shallower DOF less difficult and the YI M1 will deliver more detail with its extra 8 Megapixels. Greater resolution will allow you to crop images a little more aggressively. The more recent A7S III should have an advantage in sensor technology.
