Clearly, the two cameras have different resolutions and different sensor sizes. The KP using its bigger sensor will make getting shallower DOF easier and the Pentax KP will provide you with extra detail using its extra 14 Megapixels. Higher resolution can also allow you to crop photographs a bit more aggressively. The more recent KP will have a benefit in sensor innovation.
