If you like ice cream, you're probably already in one camp or the other. Few people claim to love Ben & Jerry's peacenik-y, tied-up-and-twisted flavors equally as well as the upper-crust uber-richness of Haagen-Dazs' highly-crafted premium varieties.

Oddly, though both have such strong brand identity and have created corporate cultures that seem pure and fiercely independent, both are tiny units of much larger (and unsexy) food companies. Ben & Jerry's was acquired by Unilever plc (ADR) (NYSE: UL) in 2000, while Haagen-Dazs was acquired by Pillsbury in 1983, now a unit of the quite pedantic General Mills, Inc. (NYSE: GIS).

How is it that two ice cream companies that share so many similarities -- the same size and shape package, the same commitment to quality of ingredients, the same fierce attention to (and careful culling of) flavor rosters, the same expectations (that you'll eat a good portion of the pint in one sitting, probably alone), the same prices -- be so different? To an outsider who understood nothing of the singular pleasure of dipping a spoon into a fresh-from-the-freezer pint of a favorite flavor, well, you'd think the brands were interchangeable; that a given consumer would choose one over the other based only on the weekly specials at one's neighborhood grocery store. Au contraire, or as they say in Vermont, no way man.
