Of course Jet Black is the superior black of the two (in my opinion). It is much deeper, especially in the sun.

I was at the dealership recently and had the opportunity to compare my car (135i Jet Black) right next to a Black Sapphire 335i which was the better looking car by design I might add.

We (myself, the dealer and assistants) all agreed that Jet Black was superior. It was pretty obvious. The reflections are much clearer. I could imagine a Z4 in JB...it would look very slick. My car had a coating of dust on it too.

My previous car was metallic black and the car before that jet black. I detail cars as a hobby so maintenance isnt a problem. Both will show swirl marks easily if not properly cared for.

Summary: if you like BLACK then Jet black is the best black.
