the alpine will give you slightly better sound quality. I personally wouldnt buy the panasonic because of all the finger prints that would cover the display from poking at it all the time. But panasonic does make good products. The alpine may be slightly easier to use too. The panasonic display would probably be very hard to see in sunlight... although it would be sitting pretty low in your dash, so it might not be as much of a problem. With the alpine you'll always be able to see the controls no matter how much sun is hitting it.
