Da Bomb: you only need a micro dot in a big bowl of soup. If you smell it, you could get breathless for a while, red in the face… and all that good stuff.
Dave’s Insanity: comes with a disclaimer. It’s not as bad as Da Bomb though.

My favorite hot sauce is texas hot sauce, i use it in everything that is not desi. Anyway, I would say it is not the ultimate stuff. Ultimate would be chinese hot sauce (sambal oneik... the name is something like that) and a dot goes long way...
