It's definitely one of the most vinegary hot sauces, but tabasco peppers have a definite flavor. Tabasco brand has 3 things going for it, stability, reliability, and longevity. It's the Budweiser of hot sauce, and you can keep it in your cupboard forever.
It's great on eggs, one the best pairings for a fried egg out there. Otherwise, it's just popular because it's around and familiar.
Some of the vinegar-based competitors have a little more flavor, but they mostly have less of a kick [Frank's, Cholula, Texas Pete's and Louisiana you can drink like kool-aid]. Sriracha has the kick, but can be too garlicky for some uses.
Tabasco is best for either eggs, . . . or when you simply need a vehicle for capsaicin.
When I need the kick, these are my preferred delivery systems.
or skip sauce altogether and sprinkle this
