I have mentioned this before and will say this again to emphasize. The reason I tried Optimum Nutritional Gold Standard 100% Whey is because it was almost always listed in the top 3-5 in surveys regarding the brest proteins.
This also applies to O/N Casein Protein.
Overall, it seems to score higher almost all the time. It is the most consistent rating and deserves it. What makes it even beter is that it also tastes better.

Mixes up really good, no clumps or anything. Vanilla ice cream tastes great . Double chocolate is ok. Definitely going to try out some different flavors.*

Good, solid, clean protein....probably why it has been around so long. The "gold standard smell" takes me back to when I first got into this game!*
