Normally, it is difficult to visualise the gap between sensor sizing purely by checking specifications. The graphic here may give you a far better sense of the sensor measurements in the G100 and A330.

To sum up, both the cameras offer different megapixel count and different sensor sizing. The G100 because of its tinier sensor will make shooting shallower DOF tougher and the Panasonic G100 will resolve extra detail as a result of its extra 10MP. Higher resolution will also let you crop pictures a little more aggressively. The more modern G100 is going to have an advantage in sensor innovation.
