Summary
The D750 is equipped with bigger sensor compared to the Pentax KP: Full frame (35.9 x 24 mm) versus APS-C (23.5 x 15.6 mm).

This option gives the camera owner more control over colour. The D750 offers more focus points than the Pentax KP: 51 vs 27. More number of focus points means less risk of losing focus lock during following a moving subject.
The D750 display is better as it offers more screen dots 1,229,000 in comparison to 921,000 dots of the Pentax KP screen. The higher dot count display is better for reviewing photos on your camera.
