I've been thinking for a while about getting a bottle of Gibson's Rare or Wiser's Very Old 18Yr. whiskies, but I'm wondering how much of an improvement I would be getting for the extra money. Both bottles go for $40 in Ontario, and for that kind of money I'm usually inclined to spend a few more bucks and get a decent single-malt or a small-batch bourbon. But every time I pass them in the LCBO, I am tempted.

So my question is, has anyone here done a direct comparison between the standard bottlings by these brands versus the 18yr. bottlings? Do you feel it is worth the upgrade?
