It really depends on what type of food I'm eating. I like Tabasco with things like pizza and eggs. If I'm eating Asian food, I prefer Sriracha or Sambal (or pretty much any other Asian chili sauce/paste). If I'm eating Mexican food, then I like Tapatio or Cholula. I love spicy food of almost any type. Indian and Thai are probably my two favorites :)
The cheap Louisiana hot sauce is barely tolerable; Tabasco is too hot for me. I don't use it often. I like a little horseradish on a roast beef sandwich too.
Don't have a "brand" but I prepare my own from ingredients I get at farm stands and supermarkets. Green salsa and pico de gallo - chopped salsa. Cut up tomatoes, jalapeno and serrano and cayenne peppers, onions, garlic, cilantro or tomatillos. Add a little salt or in summer lime juice and enjoy!
