Laphroig is my absolute favorite. It took me several tastings to get into but now I'm hooked. I have only had the 10yr but I hear the 15, and the quarter cask are even better.
For speysides I just found a nifty one called balvenie doublewood. Its aged 12 years, the last in a sherry cask. Its good stuff.
I have always like abelour, which I still do. But these two opened my eyes.
