Alright, for basic sauces:
Tabasco (original) is just peppery vinegar. It's nothing special, at all.
Texas Pete, Frank's Red Hot, Crystal, Louisiana Hot Sauce--these were good to me when I was a kid. There is a time and a place for these types of sauces.
HOWEVER--two sauces with similar tastes both do it better. Valentina, and Tapatio.
Now, getting into specialty sauces, and hot-head sauces:
Chipotle Tabasco is delicious. Great on pizza and sandwiches and whatnot. It's mainstream, but it's not your basic pepper/vinegar sauce, because of the smokiness.
El Yucateco makes a lot of great sauces. Their chipotle sauce and their basic red sauce aren't as good as the rest of the catalog, but if there is any kind of El Yucateco on the table, I'll use it. Caribbean, Kutbil-ik de (XXXtra hot), Green, Black, Red, in that order of favorites. Chipotle is shit for their brand.
Melinda's XXXtra hot is fantastic.
I'm not one to splurge on hot sauces, or purchase unknown brands, because half the time it's like $8 a bottle for something I could smash in a week, but some stuff I've had before but never bought again that I really liked:
Pain is Good Jamaican Style
Marie Sharp's Smokin' Marie's Smoked Habanero Sauce
LASTLY, a local brand. Has anyone had Blaze hot sauce?

Their Jerk Jaimaican Sauce was soooo good. Stuff's like $10 a bottle, and my girlfriend got it for me for Christmas, and two bottles were emptied by February.
I guess that's why I've resorted to trying to make my own. I just consume so much of the stuff, I have to constantly re-up. Might as well make a huge batch, and make it how I want.
