WTD: Barq's Red Creme vs Barq's Vanilla Creme (Soda Hunter)

You ever see two sodas, and wonder what the difference is between them? I found two Crème Sodas from Barq's, one was Red Crème and the other French Vanilla Crème. Without any real explanation from the labels or Barq's website, I taste them for myself to see what's the difference.
