Moonglow has a very high cool factor, but the acrylic is fairly brittle and may chip in EDC use. The blue is a very attractive blue, IMO, and a nice knife. Both have S30V blades. I think the blue was a 600 piece run, and I think the moonglow was the same, but there is still the possibility of a second 600 piece run on the moonglow, I believe, so if scarcity is a factor, you might ponder that. I have both - if I had to choose, I'd probably go with the blue. YMMV.
