Rum: Rhum Barbancourt 15 yr. old. This is a very sweet, creamy sipping rum. Not overly fruity, which is why it is my favorite. Aged rum is a category I'd like to explore some more. Selection is a bit of an issue in my town, though.
Tequila: Sol Dios Anejo. A three yr. anejo, the agave has faded quite a bit, and the wood is at the fore. I could see this being described as a whiskey drinker's tequila. Tequila purists may find it too "untequila" tasting. Pricey, may be hard to find, but easily recognizable from it's blue pyramid bottle. (as an aside, I have to hand it to the tequila marketers for making the tequila aisle the most interesting from a visual standpoint.)
Vodka: I was always an Absolut buyer, but I really don't know much about this category.
Gin: Again, I don't know much, but Beefeater always did the trick.
Beer: Any good quality IPA for me. Ice cold, in a chilled glass........that's good drinking. The hoppier the better.
Brand, Cognac, etc.: Never tried any of it.
