I'm by no means an expert, but my current top shelf choice is Glenlivet Archive 21. Rich and smooth. I try to get a bottle once in a while to celebrate special occasions with, but at $200+ it's not doable often. My last bottle was a gift from a whole team at my last job when I left. I miss those guys...
Others that I really enjoy, in no particular order, are:
Tullamore Dew (probably more due to good memories, but hey.)
Glenmorangie 18
Green Spot (really a surprise here: affordable and excellent.)
Johnny Walker Blue (another pricey one, but it's good stuff. Worth trying a bar for the experience but I'm not sure I'd spend the money on a bottle anymore.)
Eagle Rare (Yeah, it's a bourbon... So?

)
I'm not a fan of smoke in my drinks, so I prefer little to no peat. I just never developed the taste for it... at least not yet. I do try them when I get a chance.
Recently I've been on a gin kick, though. Not sure if I should throw those in here or start a new thread for that.
