Burger King and McDonald's both offer Sugar-Free Vanilla Iced Coffee, but they have distinct differences. Burger King's version is made with Coca-Cola's Coca-Cola Zero Sugar, giving it a unique Coke flavor. McDonald's uses McCafé Sugar-Free Vanilla, which has a more traditional coffee taste with a subtle vanilla undertone. Both drinks are low in calories and sugar-free, making them suitable for those watching their calorie intake or following a sugar-free diet. The choice between the two ultimately depends on personal preference for taste and brand loyalty.
