In the UK try a bar of Cadburys and a bar of Galaxy. To me the Cadburys bar is grainy and the Galaxy is smooth. Other people may feel Galaxy is greasy, I guess.
Neither of them have the 'snap' of a good chocalate.
My favourite used to be Michel Cluizel. There's a bit of a problem with high end chocolate, as there is with audiophiles or wine tasting. "It sounds nice" or "it tastes nice" are all that matters (after you have a minimum quality) but high end products make odd claims. I am doubtful of the effect of 'single plantation beans' on the end product. I'd like to see double blind trials on that.
Apparently this clown did. Real chocolate is bitter, so it is no surprise he might like the inferior Hershey's version.
I suspect it's a similar phenomenon with people who prefer HFCS Coke to cane sugar Coke. If you're used to palm oil, cocoa butter will make your chocky bar taste "off".
