Zeality is correct on both counts; cream soda (or "cake-in-a-can" as my friend calls it) is better than cola, and soda is the proper term, not pop. He is incorrect, however, in his assertion that cream soda is the finest of sodas. That is reserved for orange-cream soda, but he's not far off the mark.
Also, for those who are complaining about the flavor of soda from cans or cups, why are you drinking from anything but chilled glass bottles anyway?
