as far as taste goes, i love Grow! chocolate. unfortunately it hasn't been sitting well with me and i'll be switching after I finish my current supply.
a few years ago i was a huge fan of gnc wheybolic extreme 60. It was surprisingly affordable when they ran buy 2 get 1 free sales and it was mostly whey isolate and digestive enzymes along with a small amount of carbs. unreal flavor, but then they switched to the "amped" line of products and it's like 20+ bucks a pound so screw that.
my next order for whey will likely arrive in bags, even though the taste isn't very pleasant. the plus sides are that the price is low and that it doesn't upset my stomach.
i'm not actually a huge fan of the taste of met drive LC by itself. chocolate mixed with half water and half coconut milk is like heaven though. i'm not a huge fan of having shakes instead of meals, so i mostly order it for my fiancee. she's not adventurous enough to try some of the other flavors, although i might tack on a tub of banana next time i order some for her.
