If I had to rate flavor intensity, I'd say Teacher's (with Ardmore as a fingerprint malt) and White Horse (with Lagavulin as a component) are the smokiest and have some presence of peat in the mix. The Ballantine's Finest and Famous Grouse would similarly stand shoulder to shoulder, with the former having a touch more smoke and complexity. But I would not call any of them necessarily better than the others because I think they are all quality blends that satisfy different tastes. I personally drink more of the Teacher's and White Horse than the other two, but that's just the way my tastes run. My brother prefers the Ballantine's and Famous Grouse, so who's to say? There's always room on the bar for one more bottle, so start sampling and let me know what you think.
