I've mainly eaten the legume varieties and have been fairly pleased by them. Actually, I think I've eaten all the legume varieties from Tasty Bite, Maya Kaimal, and Truly Indian. Those are the brands I have available locally. I thought some were better than others but didn't find any to be inedible.. I keep a few around because they're so convenient.
FWIW, here's my rating of them. The numbers are just my relative rating to help me remember which I've liked better than others and not meant to render judgment on how good or bad they are. I've tried a couple of the non-legume Tasty Bite (Bombay Potatoes and Mushroom Masala) and thought they were decent, as well.
