Pepsi packs more calories, sugar, and caffeine than Coke. "Pepsi is sweeter than Coke, so right away it had a big advantage in a sip test. Pepsi is also characterized by a citrusy flavor burst, unlike the more raisiny-vanilla taste of Coke. Pepsi has more sugar, caffeine, high fructose corn syrup, and citric acid. Coke is healthier than Pepsi because although it has more sodium, it's not a significant amount to outweigh Pepsi's higher amount of sugar. In my opinion I like Coke better.
