More often than not, it's difficult to envision the contrast between sensor sizes merely by reading technical specs. The picture here will help give you a stronger sense of the sensor measurements in the K-3 II and S1.

As you have seen, each of these cameras posses different megapixels and different sensor sizes. The K-3 II with its bigger sensor will make shooting shallower DOF less difficult and the Pentax K-3 II will offer more detail with its extra 10MP. Higher resolution will let you crop pictures somewhat more aggressively. The fresher K-3 II will have a benefit in sensor tech.
