B&W versus Color

When editing, one of the decisions I make is whether I convert an image to monochrome. I've found that many intimate moments lend themselves to this type of processing and I am just naturally drawn to the look of black and white photography. I often use it when I take pictures of my girls as it really makes the viewer focus on the feeling of the image and the relationship between the subjects in the photo.

This past weekend my little rascal was climbing trees and just looked so serene laying against a branch.  I am torn for this image however, whether I prefer the black and white or color version.  Which one is your favorite?
