Not so hot?
I'm guessing that "Creamy" means cream soda, which is far too sweet for my taste. I can't even imagine what the coconut part tastes like, but highly doubt there is any natural flavoring behind either of them. If this is the case, they shouldn't even be calling it Dr. Pepper, which is at best a last resort if I'm wanting something fizzy. Right now there's only tonic and seltzer water in my '52 Kelvinator.
The only additional flavoring I've ever liked and pretty much came and went back in the '60s was Royal Crown's "cola with a twist," which came in a returnable glass bottle as sodas all used to, and had a touch of real lemon flavoring and seemingly no extra sugar, which gave it a mildly tart finish.
