Ardbeg is a great distillery, but it's produce are some of the most peaty you'll come accross. Lagavulin falls into the same catagory, big flavour, lots of peat, seaweed, iodine and medicine-like phenols.
Not whiskys for the faint hearted though....
The Balvenie Double Wood is very drinkable a good recomendation for anyone wanting a whisky with a little more flavour than the average Speyside.
Irish Whiskey, not found one I like yet. Each to there own I guess.
Famous grouse, A blend of The Macallan, Tamdhu, Glenglassaugh and Glengoyne and I guess there must be some grain alcohol in there aswell to make it a blend rather than a vatted malt? There are better drinks out there but at least you can mix it with coke without being crucified (not that mixing a whisky with coke is a good thing).
As for other blends there are some that can easily compete with some single malts, try TE BHEAG if you see it, YUM!.
If I wasn't so hung-over.......
