To date I've now had Black, Double Black, Green and Blue, the first of which I don't care to ever buy again, and the other three I enjoyed, although I'll say it again, the Blue is far more expensive than other blends I like a lot better.
The Taketsuru line of Nikka blends, at least starting with the WWA 2012 winner are very affordable in comparison, and I suppose I need to try them side by side some time.
Hibiki 12 and 17 blends are much more to my liking, particularly for their price points.
Look forward to trying Gold and Platinum at some point, but Blue will probably not ever land in my shopping cart until the price gets cut down a lot.
It's definitely good, but not for the price.
Right now my favorite is the Green, and I think I'll have a taste tonight.
