As you have seen, both of those cameras enjoy different megapixel count and different sensor measurements. The G900 using its smaller sensor will make shooting shallow depth of field harder and the Sony A9 will provide more detail because of its extra 4 Megapixels. Greater resolution can also let you crop images far more aggressively. The newer G900 will have a benefit with regard to sensor innovation.
