In my opinion chocolate is ok with milk, but not so great with water. Vanilla is pretty good with milk or water. Strawberry is awful unless with milk and even then its hard to tolerate. With water is rediculous. I accidentally picked it up.
I think you should buy the chocolate, it has only 3 grams of carbs and 1 gram of fat, and its tastes the best by far, vanilla is ok in milk, and strawberry tastes like crap IMO.
everyone is different you might like vanilla with milk but i did not.
i've never tried strawberry or the chocolate one but might taste better than vanilla.
