I loooove fage too, but it has less protein than chobani and more fat. My favorite is the cherry fage. The honey one is decent too.
Fage is creamier and tastier, but again, has less protein. I eat fage when I want to simply enjoy a good greek yogurt, but chobani is my go-to after I work out.
What flavors have you tried? That's the key. Strawberry banana is the shiznit and I don't like the others. Cherry is alright, but that's about it.
strawberry banana is the only flavor I go for!
