I hate to say this BUT, the best protein drink is the one you can tolerate. You'll get about as many different opinions about what is 'the best' as you will find different brands of protein. What I love, someone else thinks tastes like puke and vice versa. The link in the first reply to places you can buy samples is an excellent place to start. Don't waste money on tubs until you can narrow down what you like. On the pre-made drinks, if you can just buy single bottles and not packs, until you find what you like.
