I have enjoyed all of them, except the #1, which I am yet to try. I enjoy the #4, the number 2 was very good, the #3 floored me. I would say the #3 is my favorite so far. But for the price, I buy the PSD#4, and keep them in the rotation. The PSD#3, I have 2 left out of a 5ver I acquired in a trade, I will smoke them on special occassions, but will never be in my regular rotation.
