Great idea for a poll Bud! And, it's so funny to me how strongly some folks I've met in my "real life" feel about this subject.
I rarely drink soda, but when I do I definitely prefer Coke. Pepsi is too sweet for me in most cases.
On the even more rare occasion when I do crave a really sweet/dessert-ish soda I go for something really markedly sweet like Cherry Coke or even cream soda (I actually totally love cream soda as a treat). I also quite like Dr. Pepper when I'm in the mood for something really sweet. But, I only drink these things once in a blue moon. A real fountain-made old-fashioned Cherry Coke really can be delicious... and just so different from the canned/bottled kind.
