SOBE No Fear is the only one that does not tasty like medicine, but I also enjoy Blue Monster at room temperature and a little flat.
I would have to say that the SOBE Adrenaline tastes like orangina. Not bad for an energy drink!
Diet Red Bull - tastes like piss but nobody drinks an energy drink for the taste right? i usually just crack it open and down it. definitely gives me a boost for a few hours and it's pretty guilt-free.
