I try to drink Diet. I really do. I can't. It tastes disgusting to me...I'm not a fan of the regular either.
Pepsi. It tastes better... plus my Theology professor said Coke was a really immoral company and they killed some union workers.
I had some Coke with sugar in it (not corn syrup) in Europe. I didn't find the taste very different but it took less to quench my thirst.
I like Pepsi better than Coke but I like MT. Dew the best. I really liked the Throwback stuff that came out a while back. I lke the Game Fuel that's out right now. Good stuff.
Pepsi has more of a specific taste to it and has more of a bite. Coke is has more of a general cola flavor and tastes sweeter.
