I tend to like the Highland, Lowland and Speyside Malts best - which means I'm not that fond of Islay whiskies such as Caol Ila (tastes like boot polish to me) and Talisker (tastes like whisky with a small amount of boot polish to me), even though I unfortunately own them. Talisker Skye I like better than Talisker (less boot polish). Lagavulan and Oban 14, are pretty good too.
Islay whiskies are considered the real man's drink because of all the smoke and peat.
Though the whiskey that I really strongly dislike is Glenfiddich - I tend to give it to friends to drink at card nights.
Recently I discovered Johnny Walker Green Label which is always on sale everywhere. It is a mix of four single malts (including Caol Ila). Every other mix of single malts I've bought tasted dreadful, but Green Label surprised me.
Anyhow, the link below gives you a good idea of the various types of whiskies, though its classification of Glenfiddich mystifies me (perhaps because there isn't part of the diagram labelled "nasty").
And before anyone chimes in to highlight the fact that I have previously stated heretical views here - yes, I only drink them straight as a taste test every now and then. Most of the time I just mix them with Pepsi Max.
