I've had my share of the Famous Grouse, and it is good. However, the Teacher's beat out two single malts in a recent tasting two college buddies and I conducted, finishing close to Highland Park 12-Year-Old.
I used to drink a lot of Teachers back in the late 60s and early 70s -- discovered it when it was the top-rated Scotch in a Consumers Reports test of a couple of dozen top brands, beating out Chivas Regal and Johnny Walker Black, among others.

My current favorite, hands-down, is Highland Park 18-Year-Old. I drink it neat with a touch of water, which brings out the aromatics. But I also like Lagavulin and never turn up my nose at any Macallan's. Not a fan of Talisker or Laphroig, however. BTW, none of these qualify for the subject of this thread, namely cheap booze.
