I will gladly consume soft in either the corn or flour variety. I put both because in most cases, you pick the variety that suits the filling. For example, soft corn is the go-to for seafood, but the choice for flour and other proteins may depend on other sauces, marinades, or fillings. Tortillas, in general, are tricky because I don't like any of the name brand store bought ones. The texture and taste are a turnoff. All of the supermarkets here also sell fresh tortillas made daily in the bakery, so that's the only way we're having taco night at home. Although, the bakery made ones are typically more of the flour variety vs. corn. If you ever get a chance to try homemade corn tortillas...jump on it! Sooooo good!
Hard tacos and tostadas are hard pass. I shift into nacho territory if I want that kind of crunch.
