I personally prefer Pepsi because it is a sweeter taste. Ive recently learned Im a diabetic so I started trying sodas that I have tried before only in the diet category. I tried diet Coke and it is bitter and has a terrible taste. I asked around to see how others I know felt and they said that diet coke is the worst diet soda on the market. Its sad but very few restaurants cary pepsi products and the ones who do dont carry diet pepsi. This is sad! I end up paying a fortune for unsweetened tea in restaurants or drink the regular sodas that Im not supposed to drink.
