In many cases, it can be hard to see the difference between sensor dimensions just by checking technical specs. The image below will give you a much better sense of the sensor sizing in the TG-630 iHS and RZ18.

As you have seen, both the cameras feature the identical sensor size albeit not the same megapixels. You should count on the Pentax RZ18 to resolve greater detail using its extra 4 Megapixels. Higher resolution will help you crop pictures way more aggressively. The newer TG-630 iHS is going to have an advantage when it comes to sensor tech.
