Hmm. I'm usually a beer guy.
If I'm going for taste, I prefer a dark beer.
Schells is a local brewery I'm quite fond of. In particular their
Caramel Bock is to die for (not as sweet as it sounds - like the unsweetened flavor of caramel in with a good dark bock). Otherwise Negra Modelo's not bad with a slice of lime. I'm quite open to good dark beers (I love trying new micro-brews).
If I'm playing drinking games, I prefer either a light beer or a mixed drink. Also, ice cold Rum is awesome (usually Captain Morgan's Silver - very smooth for the price) and if I'm really going for drunk my friend and I usually share a bottle throughout the night just taking draws off of it.
