I shoot both and the reasons vary. At one time I shot B&W for economy, but now I find B&W an appropriate tool to emphasize composition and lighting. It tends to work well with some of the subjects I often turn to lately -- old "infrastructure," decaying industrial sites, etc. It should be noted that many painters often start with a small loosely rendered monochrome "value study" before proceeding to the final work, it's a way to "see" the foundations of an image.
the seemingly endless variations of monochrome I'll consider colour, but I think that is a long way off.
