I'm not a fan of black wheels...or chrome ones except on old cars.
A HUGE part of a vehicle's look and style is the wheels. The shape of the inner design, curves and angles, number of spokes, depth, rivets, etc. When a wheel is black, a lot of these details are lost unless you are up close and the vehicle is stationary. Plus, the tire can blend into the wheel which is an added negative. I personally like satin finished aluminum like Outlaw IIs or Convo pros with a little bit of polishing and shiny rivets.
I do have to say that on some vehicles where the wheel isn't trying to be "showy", I does help the in the looks department when the wheels are black.
That being said, to each is own and do whatever makes you happy. Its your truck.
