The EAS chocolate sucks worse. The Strawberry is good.
I never liked the Biotest flavors. They all had an almond aftertaste to me.
This is totally subjective. Everyone likes different things which is why I suggested buying it unflavored and mixing in Nestles Quick, vanilla syrup, fruit, ice cream, etc.
And again, how important is quality? Some crap whey concentrate or soy with a ton of sugar will taste great, but what's the point? Your better off eating a hamburger. If you're going to use a protein supp make it worthwhile -- something that's going to help muscle growth, not just fill your belly.
