Oftentimes, it is hard to visualise the gap between sensor sizing purely by looking at technical specs. The photograph below may provide you a much better sense of the sensor sizing in the TG-3 and ZS100.

As you can tell, both of the cameras feature different megapixels and different sensor sizing. The TG-3 having a tinier sensor will make getting shallower depth of field more difficult and the Panasonic ZS100 will resolve more detail using its extra 4 Megapixels. Higher resolution can also allow you to crop photographs way more aggressively. The older TG-3 is going to be disadvantaged with regard to sensor tech.
