Is all 100% pure protein powder the same, just different brands?

Question:

I've been reading reviews on protein powder, and some say that they absorb better than others and stuff. I was wondering if the really expensive powder is worth it, because I buy a powder at walmart for $12 and it has more protein per scoop than a GNC or EAS powder that costs like $30 for the same amount.

Is it just a gimmick, or does it really perform better?

BOTH ARE 100% PURE PROTEIN POWDER.

And since i'm asking.are protein bars better than protein powders??

Answers:
there is a difference in what pure protein could mean. just check to see what kind of pure protein they are. whey is usually the better one. some times they are soy based protein, etc. and with the more costly brands, they usually have other ingredients to make it absorb faster or to make it taste better. i havent tried the walmart stuff so i wouldnt know. but usually, the extra cost comes from buying a name brand and for a little more assured quality. just a little... i doubt theres too much of a difference.
