I love the colors, but I always prefer colors. :)
I opened your link, saw the coloured daisies and went "ahhhh..." , scrolled down to the next shot and went "ooohhh". So in answer to your question I don't know because they both had a very positive reaction - although I'm ever so slightly leaning towards the b&w. Lovely stuff.
I can't decide either, the two edits are great, really good capture in the first place :)
I love the dramatice b&w!
Both are very pretty - I'm leaning to the colour one though . . .
