I've been using this product alot lately and would rate tha flavors in tha following order when mixed in water ( milk is another story ):
Vanilla Caramel... says ALOT as I don't like ANY vanilla flavored proteins
Chocolate Peanut Butter... more of a dark chocolate
Cinnamon Oatmeal... almost ginger snap like, tied for first in milk
*Note: for whatever reason they all seem to have a somewhat bitter taste to them that definitely detracts. Milk helps but Vanilla Caramel masks it quite well regardless.
