I just got my 2009 Mercedes C300 and obviously I need to put a system in it

so I want to keep the stock HU so now my choices are the JL piece and the Audiocontrol Piece.
I would like to know which one is better and some detail would be nice, "beacuse" wont help me.
I will be putting in subs, and mids also. with 2 amps
thanks
