I think that for the most part, you get a similar buzz from MOST energy drinks. If you drink them all the time, you can notice a difference from one to another. Coffee is wicked though, what the hell is in that shit, crack?
It tastes horrible, and is about as thick as cough syrup. I would say its the best because, not becuase of its taste, but because its the only energy drink that i have actaully felt some sort of affects after drinking.
