I've tried several once at a herf, where the manager of the club was pouring for anyone who wanted to try it, and even though I was a Scotch novice I found Ardbeg to be the best I've tried. Peaty, smoky, just very rich and good. Hard to describe exactly, but she asked if I wanted to cut it with a little water, considering it was a very heavy Scotch. I told her no way! The only way to drink Scotch is neat.
