I have a small sample and I agree with you that it seems the best of the line. A simple but pleasant amber (labdanum or benzoin? I can never distinguish). I am not a huge fan of ambers to start with, and, while I like this, I think there are more complex ambers around. Still, the price is good.
Unlike you, I dislike No 6, which I find unpleasntly musty in the drydown. The other one I didn't dislike was Jockey club, which is a traditional violet barbershop.
