This is somewhat subjective -- everyone's taste is different. But I'll try to be as honest as possible.
Naturally, I think Protein Factory has the best quality and the best prices on bulk protein but I'll admit -- I don't always use their flavors! Here's my assessment of the "best of the best."
Chocolate: The ON choc is pretty good but it isn't the greatest protein. I customize my blend and get it unflavored. I then mix half Nestles Quik and half sugarless Quik and add a few teaspoons of pure cocoa. You will not find a better tasting chocolate!
Vanilla: This is a tough one. The old Blair was the best but it's gone. I actually like MetRx (which also has a hint of coconut in it) but it's so damn thick I can't have it too often. Some people like the PF vanilla but I'm kinda picky so again, I make my own. Vanilla syrup with some vanilla extrat and a a packet of Splenda works for me. Hey, you can always use Hagan Daz vanilla ice cream in it!
Banana: I'm not gonna lie -- MuscleMilk OWNS this flavor. Absolutely delicious.
Starwberry: Myoplex tastes really good but the stuff gives me the shits! MuscleMilk is pretty good but I'll mix it with my bland PF protein blend and add a spritz of sugar free syrup. That works great.
Tropical Orange. This is Protein Factory's BEST flavor in my opinion. It's freaking AWESOME. I use BIG BLAST Tropical Orange (they make a few orange flavors but the Tropical KILLS) and mix it with Sunny Delite which admittedly is high in sugar, but damn, I can drink it all day. And that's essentially what you want from a gainer anyway.
That's it. I don't go for anything fancier than that. (No root beer or mint or anything like that). I'd highly recommend you give the ones mentioned a try. You can't go wrong. But if you have a favorite, let's hear it!
