Froot soda ranked:
Pineapple
Grape
Pomegranate
Grapefruit
Orange
Apple
Pineapple Fanta used to be my favorite, but it is so sweet on my pallet now
I do love an occasional Grape Fanta or Squirt(grapefruit)
Orange is a classic
You left out Mango soda, which is amazing. Fanta Mango is CRAZY GOOD but difficult to find. When in doubt, Jarritos is sufficient
I had sparkling Apple that was sitting in the sun one time, and it was like straight piss taste and ruined it for me
