I've tried both and think they are both good Canadian expressions. They also recently added Rich and Rare Reserve- It's very inexpensive around $12 - buy this one and switch out with a friend that drinks Crown Royal. I like it better than Crown. Drew Mayville was a former Seagrams in Canada employee who now works at Buffalo Trace. He is the one who guided the development on these.
I agree with the Rich and Rare Reserve, it's a really decent Canadian at a really decent price. I like it better than Crown or Gibson's 12, for what it's worth. Nice looking bottle, too.
Life's too short, and there's too much good whiskey within reach.
