I love Amaretto, especially Amaretto sours. Also a big fan of Whiskey sours. Quality Vodka is something I can enjoy with just about any kind of mixer, and I like Spiced Rum quite a bit. Tequila liqueurs are really, really good for shots. Crown Royal is lovely.
As for beer, I drink mostly Michalob Ultra because it's pretty decent for being low carb and it's cheap. If I really want to enjoy it, then I'll get a Pale Ale. I used to drink a lot of Molson, Rolling Rock, and Moose Head.
Of course, living in the South, I often end up with cheap liquor and Sundrop. Sundrop, if you've never had it, is the king of soft drink mixers, hands down. Where I used to work, we stocked Sundrop 2-liters 3-to-1 over Coke or Pepsi just because they'd disappear over the weekend.
