One Christmas we had some Hershey's Kisses from both the US and Canada. Both tasted different. It's been a while, so I don't remember which I preferred or what the taste difference was (i.e. if one was sweeter than the other).

Neither of these are surprising. Hershey's makes very low quality products, so I would expect them to use whatever ingredients are cheapest locally.
