Vodka, it is much smoother, cleaner. Gin no matter what kind tastes kind of oily to me, I cant deal with it. Vodka on the other hand you cant go wrong with no matter what the drink. A drink like a Martini where the Vodka dominates then Absolute is the only way to go. The only one I'll drink on the rocks. Smirnoff blue label for Kamikazis of course.
I remember in the book 1984 they describe the horrible cheap gin the masses drink is described as oily among other things and it just stuck with me. All gin seems that way to me.
