Dannon is better on calories, but I would prefer to have the extra 20 calories for the wonderfully yummy taste of Yoplait. The commercials weren't kidding, some of their flavors actually taste like what they claim to be, especially the Key Lime Pie, you can even taste the butteriness of the crust.
I am not generally a yogurt fan, but the Yoplait brand Greek style Yogurt is SO GOOD. 130 calories in the strawberry flavor, no artificial sweeteners, and 12 grams of protein in a single serving! The texture is amazing too!
