Plainly, the 2 cameras offer different resolutions and different sensor measurements. The SD9 with its bigger sensor will make achieving shallow depth of field simpler and the Sony G3 will result in more detail because of its extra 7MP. Higher resolution will also allow you to crop pictures a little more aggressively. The older SD9 will be disadvantaged in sensor innovation.
