As an English person I find Hershey's disgusting, and so do all my family and friends. I have 1 American relative, and she stockpiles Dairy Milk at her house.
Hershey's is like Tesco Value chocolate DOWNGRADED, it is awful.

Chocolate in America is a risky fiasco
At least for me as I'm super picky
Hershey's is one that doesn't taste like pure wax. The main difference between American chocolates and imported is that American companies put a wax like chemical in it to prevent easy melting that is also in/similar to stomach acid.
Basically a preservative. So for foreigners who haven't grown up eating it they can taste it on potent levels
And to foreigners our chocolate tends to taste like vomit because of that chemical
