Are there brands, or models/flavors within a brand, that you feel are the only ones worth buying? I'm thinking mostly in terms of food, but I'm including the term "models" because I guess it could apply to other scenarios.
For example:
Ben and Jerry's ice cream - ridiculously expensive, I don't see it being good enough to justify the price, except for their Phish Food flavor.
Chex Mix - the chocolate Turtle flavor...while I understand that taste is something completely individual, I cannot understand why people would buy the other flavors.
