Welcome to Flame War™, where you can make petty insults, cuss like there's no tomorrow, or make a rational discussion preferring one side over the other. Each week (or so) I'll post two things that are more or less the same in terms of its own kind, and you'll just flame on over what's better. It's online advocacy, but with more insults to one's mother. Where it's perfectly acceptable to act like half your age online.
So first we'll discuss/flame:
Coke vs. Pepsi.
Begin!

The full versions of both are kind of nasty, they each have an aftertaste that I don't much like and feel thick on my tongue because of the sugar. Coke Zero and Pepsi Light however, are top notch gut rotting brews

Not only are these two variants nasty, they are also tasteless. I'd rather have some real cola instead of that weak brew.
PS: Spoiler image concerning the age old argument "Pepsi VS Cola"

There is something in Pepsi that makes me rather ill. To prove this to myself at the time with my limited knowledge on the double-blind. I've had it, and coke, served to me as simply Cola on different days.
Pepsi, if I know I am drinking it or not, makes me sick. Enough to take a day or two off work. While I'm now more knowledgeable on how to run such tests, I don't want to make myself sick, even if it is for science.

Coke on the other hand, does not make me ill. Unless I drink a stupid amount of it in one day instead of water.
It tastes best, out of a glass container, when you have not had any for at least 2 weeks.
Otherwise it's just there, and I find it good for a sugar caffeine buzz during crunch time at work.

With irc people we have made up some other flame wars threads:
Playstation3 vs xbox360
PC vs Mac
PC vs consoles
Windows vs Linux
George Bush vs Wen Jiabao (???)
Democratics vs Republicans
Acid vs Base
General racists vs Nazis
Punks vs Rockers
Painkillers vs Morphine
Hurled Brick vs Old ladies spine

Exactly why I don't go on IRC anymore.

Why the ??? - They are both experts in shoe avoidage

oh! Thats why :D Haha. I couldnt find connection between them :)

A picture is worth a thousand words

Is-is-is that Kool-aid "blood"?

these days i can't really stomach "real" coke or pepsi... its too sickeningly sweet. Coke Zero or Pepsi Nex tends to be what i go for.
Frankly I've never noticed much difference between pepsi or coke... i think its mostly in people's heads

You people should really just drink water instead.
I can't even stand the taste of hardly any soda drinks after I quit regularly drinking them.

Same here. They all taste uber sweet and you end up needing another drink 5mins later. Luckily we have very good tap water where i live :D

I'm a coke man, although I buy pepsi products from time to time. All I really care about is price and taste. I would go for the storeband soda, but seriously.. that doesn't taste good, at all.

We don't have good water but I've gotten use to it after 11 years. Plus I've had plenty worse on the various hiking trips I've been on.
