El Yucateco is habanero sauce from Mexico, comes in red and green. Not for those who think Crystal is hot.
Tapatio is popular with Southern California Hispanics, good flavor and some good heat.
Melindas is habanero from Costa Rica, nice and hot, good flavor. Just 4 drops or so on a burger gets the job done.
Another good Mexican sauce is Valentina, comes in regular (not hot) and Extra Hot (mildly hot).
Bufalo is a nice medium Mexican sauce.
Vietnam Ot Toi Chili Garlic sauce is Sriracha with seeds and membranes (that's where the heat is) plus garlic. Both made by the same company. I like it on pizza. just had it tonight, actually.
X-Treme Carolina Reaper (world's hottest chili pepper) and Ghost Pepper sauce is only for die hard hot sauce aficionados such as myself. Unless you have built up an immunity to heat, stay away. Great flavor!!!
Mild but tasty is Crystal Extra Hot and Crystal w/Garlic. Texas Pete Extra Hot is decent, too.
I am a hot sauce connoisseur, and if I didn't have a 70 pound Labrador in my lap at the moment, I'd go to the refrigerator for some more suggestions. My wife gave me my own shelf on the door, there's at least a dozen different bottles open and in use at any given time.
