Tabasco has a lot of acid and salt in it; in addition to (very minor/mild) flavor the big additions Tabasco brings to the party are Acid, Salt, and some heat. Cholula is more like a taco sauce, Tabasco does a lot to the food it is on. If you have a poor sense of smell, you'll probably enjoy Tabasco more than Cholula because it's adding a lot of chemical process, not just the minor flavor.
