Peat is sort of similar to latakia in that both impart a smoky, campfire like quality to the taste. Ardbeg is the most heavily peated scotch and if you ever get a chance to try some, you'll know peat.
My current favorites (in no particular order)
1. Balvenie 14 yr Caribbean Cask (honey, roasted vanilla, sugar cane, ultra smooth)
2. Laphroaig 10 yr (Smoky and sweet with a long finish, the best price to taste ratio among all scotches IMO)
3. Glenmorangie 12 yr Quinta Ruban port cask (sweet port cask finish, Highland finish, complex)
My ALL TIME favorite was a bottle of Glenlivet Archive (which at the time of this particular bottling, I think was a 21). It had probably a dozen extra years on it, too, but I don't know whether scotch really develops much more after it's bottled.
