As you can tell, each of the cameras provide different megapixel count and different sensor sizes. The TG-4 with its smaller sensor will make achieving shallower DOF more challenging and the Olympus TG-4 will produce more detail using its extra 2MP. Greater resolution will also let you crop pics more aggressively. The younger TG-4 is going to have a benefit with regard to sensor innovation.
