do they use real sugar?

Coke, IMO Pepsi tasts just a tad too sweet.

Neither. They are both unhealthy garbage. Water will do your body more good than this stuff that destroys you.

what's the difference?

EDIT: Oh and HIGH FIVE BTW lolololol

I prefer Pepsi but sometimes I'm just in the mood for a Coke, y'know? I'm not that picky. But I lean towards Pepsi.

Yes. You have cheap corn syrup because of subsidies. We have expensive sugar beet because of subsidies.

Quotas are stupid.

Coke always wins these polls as Coke owns the world. Sadly. It is less sweet. Pepsi is bigger in the USA and Canada, but still smaller then when it dominated in the USA  when I was a child and teenager.
In other words, the poll is worthless because many in other countries get tons less contact with Pepsi. 

They do. The difference is Coke has more bite whereas Pepsi is more smooth.

I prefer Coke, it's the only cola with that much bite that I know of. It's just so satisfying to drink.

@OP - You should change the poll later on after everyone's done voting to see who's products are better.

I'd say Pepsi tastes slightly better. But that's probably just the hipster inside me spreading his bias.
