I need help deciding which headunit is better?

Pioneer for sure! I have always run pioneer! I have had 5 different pioneer decks and never had a problem with 1 but i bought a kenwood and the face always falls off, the nob gets stuck and is just a piece of cr4p to tune! It doesnt have all the capabilities of the pioneer! The extra hundred bux or so u put into it will be worth it! I have never had any problems with mine! I am now checking out Alpine head decks and seeing how they go! Hopefully as well as Pioneer has in the past! Hope this helps. Peace
