There isn't a European counterpart to American milk chocolate (which mostly tastes like Hershey's) is there? Like, the reason they are different isn't quality, it's that they are different.

Or have you sampled American chocolates that do not try to follow Hershey's flavor and found that they are all inferior?

AFAIK, In Europe the minimum cocoa content for chocolate is 20% while 10% in the US. The US mainstream chocolate handles the lacking cocoa by adding more sugar. Of course you'll find all kinds of boutique chocolates everywhere, but the earlier anecdotes seemed to be about the cheap mainstream stuff.
