As you can see, both of those cameras posses different megapixel count and different sensor sizing. The G1 with its larger sensor is going to make achieving bokeh simpler and the Panasonic G1 will give more detail using its extra 2 Megapixels. Greater resolution will also let you crop photos somewhat more aggressively. The older G1 is going to be behind with regard to sensor technology.
