Which is Better?
 

For those of you who have had both, which is better?

The Balvenie:
12 yr Signature v. 15 yr Single Barrel?

Glenfarclas:
15 yr (Europe) v. 17 yr (U.S.)?

Full-power sherry bombs:
Glenfarclas 105 v. Macallan Cask Strength v. Aberlour A'Bunadh?

The better one is the one that you prefer. All malt whisky is personal, for example I really don't like to drink sherry whisky. If I want sherry I'll have a good amontillado not dilute my malt with it.

This'll start a heated discussion if nothing else

Yeah, that was the point. I am just soliciting opinions for the sake of discussion.

I should have asked, "which do you prefer?"

Personally, I prefer the 15yo Balvenie, I really don't like Glenfarclas but do like a couple of the Speysides, the older Glen Grants and, when I can get it Aultmore
