I voted for the Talisker. It is a whisky with staying power. It's been in my half-dozen favourites for at least 20 years. The quality of other malts has risen and fallen in that time (Macalland and Laphroiag spring to mind) but Talisker keeps going and it tastes as good now as it did in the 1980s.
Highland Park is also a favourite but the 12 just doesn't have the same luxurious quality of the Talisker.
I've only been drinking Ardbeg for three years or so, nowhere near long enough to come to a decision
Lovely stuff but a bit 'raw' to make it as a favourite.
Balvenie is okay. To me it isn't anything special, just a very nice Scotch but it isn't going to get into my top 20. I'd rather have a Macallan or Glenlivet or Glenmorangie or something.
Springbank isn't something I drink often enough to be able to offer an opinion on. Maybe I need a bottle or three to remind me...
