The taste is the main difference, theres also the look of the can, the motto, and the company.

Pepsi tastes like shit from a new born pig, and coke tastes so good that you need one more. Thats the differens!

To me Pepsi tastes flat and coke is just the BOMB!!!

Coke has a...umm...a little lemony taste don'tcha think.Pepsi has a ordinary taste (except pepsi twist and light).Oh and coke is more popular than pepsi.

I think Pepsi is a little juicy. Coca Cola has more sugar and acid in it.

Pepsi is a bit more flat. And you can taste the sugar more.

Pepsi has no carbonation in it, where Coke has great taste and has a good amount of fizz.

pepsi is way sweeter

It's in the taste. I can't really explain it but if you drink a coke, your mouth tastes really good for quite a while afterwards. It's just got a really good taste and a really good aftertaste.

Pepsi has more sugar in it or something.

it taste differsnt

I dont know but i like BOTH!!

the lable and coke taste better
