As you have seen, both of those cameras posses different resolutions and different sensor measurements. The K-3 because of its bigger sensor will make shooting shallow DOF less difficult and the Pentax K-3 will deliver extra detail due to its extra 4MP. Higher resolution will also make it easier to crop shots somewhat more aggressively. The more modern K-3 is going to have an advantage in sensor tech.
