Clearly, both of these cameras offer different megapixels and different sensor sizes. The G3 X due to its larger sensor is going to make achieving shallow DOF less difficult and the Canon G3 X will deliver extra detail due to its extra 8 Megapixels. Greater resolution will also help you crop images a little more aggressively. The newer G3 X should have a benefit in sensor tech.
