Generally, it's difficult to visualise the contrast in sensor dimensions purely by viewing a spec sheet. The image here will help provide you a greater sense of the sensor measurements in the G100 and S1.

As you can see, each of these cameras posses different megapixel count and different sensor dimensions. The G100 using its larger sensor will make shooting bokeh easier and the Panasonic G100 will result in more detail because of its extra 6 Megapixels. Greater resolution will also make it easier to crop images somewhat more aggressively. The younger G100 is going to have an edge with regard to sensor technology.
