Diet coke is better then regualr coke, ill give it that. COKE its self is bitter. Coke is bitter because it has less sugar then pepsi.Diet coke really is something that should be avoided at all costs!!!!!!!! The aspartame in diet coke makes coke tast better then regular coke. Even though coke been around longer then pepsi, pepsi is SOOO much bettet than ANY cokes products. Coke itself would not be a brand if it wasnt for the other products in the coca cola company. so the next time you drink a diet coke, thik of what I said and just go with your own taste!
