One issue I have is with tequila - is this a typical wedding liquor choice? What do you mix it with that isn't a margarita?
Ever Mexican wedding, man? Tequila is a staple. You can mix it with coke (called a charro negro), you can mix it with any juice (my preferred is grapefruit w/shaved/crushed ice), you can sip it neat. For cryin' out loud, if you're on spring break in South Padre or some such hookup festival you can shoot it six ways to Sunday.
I answered tequila (I'll take mine reposado, neat, and just about anything but generic or Jose Cuervo: prefer Herradura or Jimador if you have 'em). If I want a changeup or to feel refreshed I'm going to a white tequila w/grapefruit juice (or just water, I KNOW, not on the list).
That being said, I really don't dislike ANY of the choices listed (do I have a problem?). In order of favorite to least favorite (but still pretty good):
Tequila > Bourbon > Scotch > Rum (if it's a Caribbean wedding, I'm going here first & probably all night long) > Vodka (if it's a Polish or Russian - even Ukrainian - wedding I'm going here first and as long as I can last) > Gin (hardly EVER drink this because other choices are usually readily available)

Everybody!
