High end (meaning high price) Cognac is not necessarily good. Sometimes, there is no relation between what you pay and what you get. My favorite Cognac is
Delamain. I was fortunate to be able to obtain a bottle of the Reserve de Famille, aged for 50 years. To my understanding, it is no longer available in the US and my wife and I finished it long ago. Extraordinary! I have not liked any of the Hennessy Cognacs that I have tried.
That said, I prefer
Armagnac and the best Armagnac that I ever had was also fairly cheap.
