They are both non-caffeine and lemon-lime so they would have similar tastes and appearances.
personally i think sprite is sweeter, i also think pepsi is sweeter than coca-cola. don't really know if that makes sense considering the above bold sentence.
and for those who doesn't think there is a difference, i think you're wrong. yes they have the same flavour lemon-lime but they are made by different company's and even if they have the same recipe (which i doubt) they would still taste different.
If I remember correctly 7up has a sweeter more lemony taste. I think Pepsi tastes better than Coke. I swear that Coke's flavour has changed greatly over the years. Its more fruity now imo.
Sprite is more popular, isn't it? Haven't had 7Up for ages. And I prefer Pepsi to Coke But then there's all different flavours now, like Pepsi Max Coffee Cino, Diet Coke With Vanilla and all that...
Now here's a question, what's the difference between Cherry Coke and Diet Coke with Cherry?! I haven't tried the latter, but surely they're the same?
That's like asking 'What's the difference between Coke and Pepsi?'. The answer - nothing.
Coke tastes stronger than Pepsi in my opinion, so I prefer Pepsi. However I like Sprite better than 7up. Probably because it's always available and more popular.
I like sprite better. I think it has more of a lemonny lime taste. I think anyway. Actually, am not really sure it does. It just tastes better-don't know why.
