As far as non colas go I have been drinking sprite for quite some time and really enjoy it but still felt thirsty afterward.
Recently 7-up was on sale and I havent had it in years so decided to try it again and find that it quenches my thirst a lot better and the taste is nearly the same.
I have never actually compared them side by side but I do not see much difference in the taste. I do however think that it holds the fizz much longer and that is what I am drinking as I write this.
I will be sticking with this one from now on and would recommend it to others.
It comes in all size bottles, cans, multi-packs and the price is the same as any other soft drink.
