I love the original Dave's insanity I find it to be hotter than every other one of there's I have tried and the taste is a lot better, at least in the foods I eat, I have tried the habanero and the ghost pepper ones, and while you think they would be hotter to me they aren't and also they tend to change the flavor of my food too much.  I plan on trying some of the others they make but until I find one better this is my top choice out of the three.
