I bought a lot of the samples and while Chocolate Mint was good my fav still has to be vanilla! Just for the fact that it actually tastes decent AND it mixes well with everything. You can mix fruits with it, peanut buttter (and whatever other fats you want), put it in your cereal/oatmeal etc. basically vanilla goes with so many things and is really versatile, whereas Chocolate Mint, atleast for me only goes well just straight with milk nothing else.
