If you like it, you like it. Personally, I dont use EAS, I have always used Creatine Mono (prior to my MuscleTech trial) made by nutrabiotics, and my whey is 80%.
EAS is decent. Protien, many like Muscle Milk, 0311 will say NLarge, ON is good, I think they sell a 10lb sac at 1fast400.
I had the MRM brand, and I thought it was tasty. Your best bang for the buck would be Nlarge, or a pro powder in bulk from trueprotien or the like.
Most creatine, glutamine, and the lot are manufactured and the same quality as each other, Creatine Mono is extremely common.
Try a CEE and see how/if you like it.
