Fair point re: Carolina Reaper, but come on re: Frank's, that's just insulting, man!
Franks is a perfectly serviceable source of flavor. More on that below.
We have that over here too. It's an absolute joke of a hot sauce even if it goes well with certain things. It's 450 SHU. Even Cholula, which is barely hot, is 1000 SHU (I have both in my fridge right now).
Okay, so, let's go there, shall we?
I am sure you are aware that the original Scoville Heat Unit was a
subjective assessment. And, even with modern direct measuring of chemical concentration, the
human experience of heat is still subjective - how you assess it will depend on the palate of the individual.
Of specific note - if you constantly bombard your mouth with hotter and hotter flavors, you become
desensitized, and need more and more capsaicinoids to get the same sensation.
Many of the peppers used to meet the needs of those who have desensitized themselves to the heat actually don't have a lot of other flavor of their own besides heat. Notable exceptions, the Habanero and Scotch Bonnet, have a decent fruity flavor... that will be totally overwhelmed and undetectable if you
haven't desensitized yourself to the heat. The pepper is nigh useless to those who haven't been taking in a diet of higher and higher levels of capsaicinoids.
Franks is a general purpose sauce, with a pretty decent
flavor, besides its heat. It is a good product for people who haven't had a constant diet of heat. This probably aligns pretty well with WotC products.
Tabasco is well-known to be hotter, but has little other flavor to it. Sauces hotter than that are largely useless except to the officionado.
