I don't really like the Regular Pepsi or Coke Colas, however, I like Pepsi Twist and Vanilla Coke more, but I like Cherry Coke better than Cherry Pepsi.
Dr. Pepper is my favorite, Mt. Dew is #2 favorite... But I have to want them to drink them, I don't like Dr. Pepper everyday, so Mountain Dew is a good alternative.
Oh, and Root Beer takes the cake on all sodas.
