Spiced Rum [captain morgan, others], I try to stay away from just because of, well, the spice.
Bacardi and coke is the most effective and tasty thing to get me gone the quickest. The carbonation helps eat through any food you may have had. And if you haven't eaten, it flies right through you, so you feel it quicker.
Smirnoff is also excellent.
Beer, not so good. If it's at a party, sure, pick one up and walk around with it, but to regularly drink them to get drunk? No. It's all about liquor.
