Lately, I've tried and liked the Aberfoyle, as well.
It's my Scots ancestry....nothing beats a wee dram of the GOOD stuff, even if it offends my Scottish wallet sense!
I've had several different Laphroaig's, including a rare bottle of 40yr. They do get progressively better with age, though I find the really young stuff pretty mediocre. I am an Islay bigot, but my preferred drinking scotch is the classic Lagavulin 16, which really hits the nail on the head flavor-wise. In my opinion Laphroaig doesn't start to compete with it until you get to the very old bottlings.
I normally don't put water in my scotch, but I also have some cask-strength 29yr Bowmore currently (with bits of wood sediment in it, no less) that pretty much demands it or the strength of flavor and character will overwhelm your tastebuds. It doesn't need a lot, just a little, which precipitates some of the organics solved in it. Everyone who likes single-malts should try the unfiltered cask-strength versions that come straight out of the barrel at least once; it is something else.
