BPI sports makes great protein and they certify their products through an outside lab which is nice because you know you are getting legitimately what you pay for. The ISO HD Smores flavor was great and is only 3g of carbs and 2 g of fat with 25g of protein, so this fits in well if you count your macros. I also tried the Vanilla Cookie one, which isn't as good as Smores, but still isn't bad by any means. Mixability could be better but definitely not bad at all. The price is a little high , but it is worth it to enjoy your shake instead of just slamming it down.
