Mine would have to be Goldschläger. I tried this stuff over break with my friends and I honestly can say it was the most delicious liquor I have ever tasted in my life. I don't usually like the taste of straight hard liquor, but i was pounding shots of this stuff (its around 44%) with no chaser or problem.
