First off I am pretty sure all the Tat Black blends are the same. Obviously there are minor differences because of the size of the vitola, but they are all based on the same blend.
Second... this thread goes to show tastes are so subjective which is a good thing

I didn't think the Black Tubo was all that good when they were originally released, but smoking a couple lately I have been very pleased. My cigars are from the first release last year so they have some rest time which is needed I think, but mine are smoking great right now and I'm glad I didn't sell them off!
