What's your favourite Hot Sauce

I use Cholula as my regular and occasionally Tapatio.
I was at a warehouse in Colorado and the guys who work there are always "testing" hot sauce. Last time I was there they had some Mad Dog 44 Magnum.... that stuff makes Daves Insanity look like a desert topping!! Wow! One drop in a large bowl of chili and its a coughing, sweating, eye watering afternoon.
