It's a very nice shot and I love the light streaming through the clouds. I too give the nod to the colour version but possibly for a very different reason. I'm at work so my monitor isn't as good but it looks like the image is a little underexposed and there seems to be a fair bit of noise that I don't notice as much in the colour version. I'm partial to colour in general so I prefer the colour one but I think the black and white could look much more dramatic with the right adjustments.
