Protien drinks

So, can anyone tell me what they think the best protien drink is?

I have tried them all, and the only one I can tolerate in a powder form is the one from walmart. It has 20 gm of protein per scoop, you put it in milk (4 oz.), skim. It becomes a thick shake and I swear it is almost like nestles quick. Put it in the freezer for a few minutes and its great. The other protein drink is at GNC and it is ISOPURE, has many flavors, Icy Orange is my favorite, has 40 gm of protein but it is around 3.50 per bottle. The Walmart product is called Body Fortress and sells for 11.97 for 30 servings, a great bargain, comes in chocolate, vanilla and strawberry. Trust me its the only powder out there that is easy on your taste buds. Barb

Is that protein from Walmart a walmart brand? If not which brand is it.
