I like bananas, but I hate banana flavored things.

Moi, I am your direct opposite! I love nearly every type of cherry out there (maybe not a few of the sour-bitter wilder varieties), but the cherry-flavored items not at all. To me they taste more like super-sweetened apple concentrate with some almond flavoring mixed in. Somehow. I'm not quite sure how to describe it, but that seems about the best way...
(And I do like actual apples. And almonds. And even sweet things. It's just that particular combination somehow?... there's something else to it though. Because if you chop up apples and toss them in sugar and bake them, with maybe a tiny bit of cinnamon and lemon juice, and then spoon that baked mix into almond-paste shells? then it makes a FANTASTIC dessert. So that description isn't quite right either.)

I generally like the artificial flavorings if I like the natural kind, though there are some that are not made well. Like some fake cherry flavored things taste different than other fake cherry flavored things? I don't like them all across the board.

The reason that fake banana flavor doesn't taste the same as real bananas is because the species of banana that the fake flavor is made to resemble is extinct.
