You can get the Vanilla one here in UY (not locally made, imported), and it tastes absolutely awful. Way, way too sweet.
Didn't know you had it over there, wish I had known that when I used to go on vacation with my family to Punta del Este many years ago.
I tried it in New York last year and liked it a lot. It was sweet but not excessively so, unlike Cherry Coke which didn't fit with McDonald's food at all. Lime Coke wasn't bad either, although I prefer Pepsi Twist. Didn't get to try Cherry Vanilla
Man, that soda machine in McDonald's and Five Guys was awesome. If they brought that here (with all the flavors, of course) I could die happily.
