If you have to have one of those three entities i'd say Pepsi. And the logo kicks ass all over coca colas. Notice the capitals for Pepsi and not coca cola. It's like.......the boss or something.
Also the Pepsi logo is Taoist and Kabbalistic. A very kick-ass sigil bomb right there. Red and Blue symbolizing Geburah and Chesed, and in the shape of the Tao.
Mountain Dew and Dr. Pepper are two good sodas. I try to always have a 2-litre bottle of Mountain Dew by my side. The thing is that I like my soda cold and flat. Does anybody else like their soda flat? Cause I don't see the real point of carbonization. I mean, all it does is prevent you from gulping down the drink.
The best soda, including colas and noncolas, is Minute Maid Valencia Orange soda. The rest of you have been corrupted by demons of other flavors, and must be rebaptized in an effervescent orange font.
Don't drink fizzy drinks! They make your bones crumble, you know. One day you'll take one last mouthful of fizz and tumble to the ground, a floppy ragdoll.
Back before I gave Mormons a run for their money in swearing off the fizzies, I used to be hooked to Josta. It was one of Pepsi's rare attempts to imitate and sell South American guarana sodas.
