Steel Reserve if I only have a buck or two and need to get smashed quick. Milwaukees Best Light for a kick back and get drunk slowly kind of night(which usually just means that I drink 3x as fast and finish off a 12 pack in the amount of time it usually takes me to kill a couple cans of steel reserve, but it feels like it's lasting longer...).
Budweiser if I am feeling classy. But overall, the less it tastes like beer, the better, imho.
