What does colour bring to the image? For this particular image colour informs the viewer that this isn't a ripe fruit so there's a significant difference between the colour and b&w version.
Got to ask yourself what you're trying to get across with the image. If it's a straight documentary shot [a picture of something] I'd say, stay in colour. If you're trying to say something [a picture about something], then you need to think about what works best for what you're trying to say.
For example, when I saw the B&W version, I thought "strawberry", then I saw the colour and thought. "Nope". Thinking about my reply, I'd probably tackle this as a tryptich with green strawberry on the left, a red strawberry on the right (the same one when it's ripe probably, or even the green one recoloured) and a black and white version in the middle that is something else (either another shot when it's ripening or a photoshop half 'n' half of red & green). With a bit more space around the strawberries and going square with each shot I think it would work well as either three panels on the wall, or a single panel with three images on it.
