As you have seen, both of those cameras posses different resolutions and different sensor sizes. The TG-610 due to its smaller sensor is going to make shooting shallow depth of field more difficult and the Pentax K-S2 will show greater detail as a result of its extra 6MP. Greater resolution will make it easier to crop pics somewhat more aggressively. The more aged TG-610 will be disadvantaged with regard to sensor technology.
