JW Red
Chivas Regal 12 (never had the 18 or 25 but I'm sure I would like it based on how much I like the 12!)
Dewars White, 12
I am not a huge of fan of the JW black.

I can't really put my finger on it but it has this sweetness that I find a little unappealing. I am just as happy with the Red for $10 less.
I saw a couple people mention Cutty Shark - is it really not bad? I've always been tempted.
