I usually drink irish whiskeys. Jamesons is my everyday whiskey, and my housemates bought me a bottle Jamesons 18 year old for my birthday which was absolutely delicious. Bushmills 10 year old is also very good (regular bushmills is fine for everyday whiskey too).
Among American Whiskeys, Wild Turkey can be quite good, Makers Mark is good, I can't stand Jack Daniels.
I had a Scotch called Speyside (that was the brand name if I recall correctly, not just the area it was from) and it was really excellent. Generally, I'm not a huge fan of scotch. The ones I have liked tend to be light on the Peetiness.
Sorry, crown royal is absolutely undrinkable. I would love to try more whiskeys from all over the world, so I'm looking forward to seeing more of what people post in this thread that I might give a shot.
