Coca Cola is absolute.

It's either 7 Up or Sprite.
Why? Coz' lemon-lime.

When talking about soda: Royal crown cola, any pepsi product, though some of the coke products are great, especially sprite and fanta, and of course a refreshing Vernor's ginger ale

When talking about energy drinks: Red bull all the way (Sorry Monster, but you taste nasty), rock star, and full throttle

When talking about alcohol: Bier (Yes, that is spelled correctly, just in German :P), and it has to be an authentic local brand of GERMAN beer (namely Dinkel Acker or Hochdorfer), not the piss flavored stuff you can get in the states. I have been experimenting with making ginger beer, because authentic organic ingredients like barley malts and hops are a pain to get to make normal beer, but ginger, a few cloves, a lemon, some sugar, a spoonful of yeast, and some honey are relatively cheap to get and easy to find here in the states. I also do like some champagnes, but it is usually only for a special occasion that I drink it.

When talking about unflavored stuff: well, sprudel (club soda) seems to be the only thing to put here

And misc.: Apfel schorle (fizzy apple juice....I miss Germany v.v)

coca cola

Sprite

Lift Lemon.

Pepsi, nuff said.
However I did buy sodastream to go easy on my wallet as I consume pepsi quite a bit ;3

I've always been a Pepsi fan

Solo would be my favorite.

Coke and Red Bull.
Not only are they delicious, but if you drink those and drink coffee you can definitely pull an all-nighter (at least for me, it works :P).

Soda stream is a good value drink.

GFuel tastes pretty good, shame about the price.

As a late night gamer it has to be Mountain Dew...

THERE CAN BE ONLY ONE!

I have a few favorites They are Mountain Dew, Sprite and shandy(does shandy count?)
