I would say Pepsi is the saving grace of Pepsi.
Love me some Pepsi- though I will agree that Dr.Pepper isn't as good as Mountain Dew. Though I don't like Mountain Dew as much as I like Sprite, and I don't like Sprite as much as I like Pepsi. Or Coke, really; they're mostly interchangeable for me- though lately I've been having this Pepsi vs. Coke taste war. It's been interesting.
