It also depends on who is looking at the image. I have found that more people are pleased with and distracted by color. Trying to make a B&W work takes imagination and effort and some viewers just don't have the patience and imagination. I personally think that Black and White is more difficult because you have more options in exposure control on the whole, such as filters, etc. and it takes a bit more knowledge to pull a B&W off that pops, color can just look pretty and fool the masses.
