I like all of Optimum Nutrition's stuff and some other company's stuff, but Optimum for the value.
I use 100% whey for just a normal powder to bulk up protein, Opti-Pro Meal if i'm taking it as a meal for dieting (if I'm not dieting I opt for food!), and Protein Diet Meal Bars. All are excelent quality I feel, and are priced really low. I also like Myoplex Strawberry! Very tasty, all I've ever had was the Deluxe, wonder if thats more tasty

, but definatly not worth the extra $EAS$ IMHO. (Although EAS is probably the leader in real scientific research so I'd rather it go to them than to Muscle-Tech for getting slim guys to blow out their stomachs for before pictures in one of their 3 5-page advertisements in 1 of 10 different magazines.)
Peace,
