My vote goes to Blairs Sudden Death and Dave's. Funny that you all mentioned them, I always thought those were small batch hot sauces. I don't vote for them to be the best tasting unless liquid blowtorch is a flavor. But they are fun to bring out when someone asks for some hot sauce.
I tried Tabasco Habanero...it was pretty good. Takes a few drops to get the heat up but the taste was great.
On Mexican food I prefer lots of Cholula hot sauce.
