well, Pepsi is my favorite soda, period.
in my opinion, Pepsi has a more crisp taste...you know, the kind where you take a drink and automatically let out an "ahh" (which does happen if you're really thirsty too, but I get that even when I'm not extremely thirsty with Pepsi).
plus, Coke has a weird after-taste to me and the taste kinda reminds me of molasses.
so really, if I want soda and they have Coke instead of Pepsi...I end up getting Sprite since that's the only option they have when it's Coke products that's good (in my opinion). lol.
