Most of the great photographers shine bright in black and white.
With colour the composition can be less tight as the eye is more easily seduced.
I love both genres but am a sucker for a colour photo manipulated with filters to create a faded/worn feel.
Happy snapping.

I think the tastes change and as @dedicatedguy mentions, sometimes colour is better which I agree with. My granddad was an amateur photographer who developed his own shots. He had a darkroom setup and even a colour enlarger, a luxury considering the time. I used to love looking through his photos.
