If you have ever tried, what's your opinion about Johnnie Walker Black Label?

I've bought a bottle yesterday and tried for the first time. It's far more better than the standard blends I had tried before-icluding JW Red, J&B Rare, etc., in compliance with the "deluxe" claim on the bottle and the maturation period of 12 years. However, bourbon continues to be my choice. What do you think?

PS: BTW, I posted a poll about JW Black Label on the Whiskey Magazine forum-you know there are mostly Scotch fans there. I'll compare the opinions of the two sides of Atlantic.
