I prefer orange soda. Sunkist is my personal favorite -- orange and caffeinated! Not sure how much caffeine it has, though... Fanta would come next, although it does taste better in Germany than the US, in my opinion. But, in most cases, orange soda is orange soda. :P After that, I'd say strawberry soda of any kind. 7UP is also good, the best of the lemon-lime sodas.
