The TG-3 with its smaller sensor will make achieving shallow DOF harder and the Olympus TG-3 will provide you with more detail having an extra 6 Megapixels. Greater resolution will allow you to crop images a good deal more aggressively. The more modern TG-3 is going to have an advantage when it comes to sensor tech.
