It's simple.   Whisky is Scotch.   Whiskey is everything else.   What do you prefer and why?   Personally, Scotch is far and away my preference. And Single Malt Scotch at that.   I've tried Bourbon... I really notice that "corn mash" flavor and it almost tastes saccharine to me. Even the more expensive bottles I've bought sporadically just to try to be part of the converted.   Canadian Whiskey is a little better, but largely the same.
