I like Coke and Pepsi.
Coke zero is gross in my opinion - so- Pepsi, even though I haven't tried it.
They are two of the word's largest beverage companies and they've always been in competition with one another.
According to Beverage Digest, Coke owns 17% of the American market for carbonated soft drinks while Pepsi owns the 8.9%.
Despite its effort Pepsi was never able to outscore Coca Cola although blind tests were carried out and suggested that people like it more than Coke, possibly because Pepsi is sweeter than Coke but the latter has more popularity and better adverts.
However I would say none of them is better over the other, because they are both bad products. In effect, these companies are having some problems nowadays because more and more people are reducing the consumption of soda or sugar-sweetened beverages like these two. That's because people are finding out about the damaging effects that these drinks have on their health mostly (but not uniquely) because of their high sugar content or similar (like high fructose corn syrup and/or aspartame )
That's also why Coca Cola is going hard on those adverts that include friends, family, music, good moments (and polar bears) instead of focusing on the taste or the quality of the beverage.
I would say that there isn't a better one, but regarding the taste it is purely individual!
Both of them are good
But I drink coke it taste goood
Pepsi is better than Coke Zero, so Pepsi.
