I'm no snob, and that Hershey's bar looks decent. What's the taste like?
I wouldn't say I'm qualified enough to pass judgment on
best chocolate ever, as there's a whole world of it I've yet to taste - mostly US and Venezuelan stuff. But since I love learning about my favorite foods, I do have an idea or two on European chocolate market...and as far as regionally available cheap, sweet, on-the-road chocolate goes,
the Toblerone beats the whole lot of Nestle, Milka and Mars inc. in my book. On that note, common Swiss stuff is usually sweet, expensive and high-grade, like
Lindt bars; those are actually affordably cheap around here. German chocolate, as a different example, generally takes a slightly more sour route and includes lemon and orange peels (nothing out of ordinary; Ritter Sport, etc. are still very palatable, just, well, not really about cocoa anymore). I never tasted Germany's darker chocolates like Feodora or Hachez, but was told high praises about the former.
Some people swear by Ferrero. It's sweet like Milka, only more creamy. I'm not a fan.
Liking my cacao more bitter than not, the crude tastes of Balkans fit better with me. Out of exotic Yugoslavian brands listed, Kraš famously produces
the Bajadera from the 1950s onwards which is
very sweet and heavy on cocoa oils and caramel, while the Gorenjka products are more adult and experimental (there's
all sorts of stuff in some of Slovenia's chocolates); I like buying and consuming both of these brands, if for differing reasons. But I wouldn't say they're the best chocolate! The best chocolate in the world would probably be something French - their chocolate makers love to take the bitter in cacao powder and make whole mansions of tastes with it. I dunno what their big name brands are, but I went to visit a French chocolate restaurant in Munich once, and ordered what looked 3-cm balls of chocolate mass dipped in raw powder. It looked inedible, like brown pebbles of dirt or something, but tasted sharp and salty where it should've been sweet and bitter by all accounts. It was awesome. (Maybe it was only awesome because it looked weird, cost me a dollar and a dime and was served by a person saying "si'l vous plait", but those facts doesn't make it any less so. >_>)
