[b](*)MyProtein has constantly revolving sales and coupons won't be able to keep up with. You can usually find a 50% off coupon if you search for one online, so I based the calculations assuming you have one, but YMMV.
Stuff I don't consider, but you are free to debate in the comments:
- Vegan, Non-GMO, Kosher, types of flavorings/sweeteners.
- Whether the supplier is honest. The supplement industry is unregulated, and I am only comparing what they claim. That may or may not match what is actually in the product, and I have no way of knowing if they tell the truth or not.
- Serving/scoop size because it is an irrelevant metric. This is normalized by giving a price per gram protein. You can adjust your servings to have as much or little protein as you want.
- Extra ingredients (wanted or unwanted).
- If you want another product considered, add a comment and add a deal so I have a link and discounted price for calculations.
- I will add and remove products, and will post a comment when I do so. If you want to stay current, subscribe to this post.

Slickdeals Frontpaged this deal, which takes away my ability to edit the main post.
They also removed several of the products in the comparison and altered some of the pricing in ways that no longer make sense (for example, they changed a 50% my protein coupon to a 35% coupon, but didn't change the per-gram price, making the math wrong).
I have put the original post in the wiki, where I (or anyone else) can edit it.
My favorite, being an obligate carnivore, but didn't include on list because it isn't a protein powder.
Thanksgiving Turkey. An 18lb bird, 59c/lb near thanksgiving, with about 7lb yield after roasting:
- 1.23c per gram of protein
- $10.62 for 7lb of meat
- 53% of calories from protein
- 27.3% of edible mass from protein
- 6.7% of protein is Leucine
I have ten of these in my freezer outside.
It's a sad day in August when you run out of Thanksgiving turkey.
Cost is not the only important thing. Some powders may have more value to you for various reasons that are not considered in this analysis, such as merchant reputability, additional ingredients like Creatine, how well it dissolves, how good it tastes, GMO, Vegan, Kosher, etc... Feel free to discuss all that here in the comments.
As an example, I think Muscle Milk is competitive. It's not the cheapest in cost/g, but it's a major brand sold at stores, probably more reputable, and is primarily whey isolate, but I am suspicious of it's low percentage protein (in both calories and mass), making me think it has a lot of extra stuff that you may not want/need.

- MyProtein Whey Isolate - $0.0302 per g protein with 50% coupon
- Deal Supplement Pea Isolate - $0.0151 per g protein
- Zen Principle Brown Rice Protein - $0.0206 per g protein
If you want me to add a product, post a deal in the Fitness > Protein Powders category:

As for the serving size, yes, I think MM contains some unnecessary ingredients that add volume and weight.
If you take a premix muscle milk and compare with a muscle milk from powder, the premix tastes much much better. Also, mixing powders no matter what they say is a nightmare. Even with a blender its pretty marginal and generally not worth the hassle and difficulty to transport.
At home, if you are serious about weights you can just eat a frickin chicken as others have said. Or turkey. The shakes are nice to be able to carry with you to lunch or whatever easily. If you have to mix it and take your own bottle, it makes it less convenient for sure.

IMO taste of protein powder >>> any other criteria as long as the cost per serving is reasonable to you. I've tried all sorts of protein powders at this point and have also thrown out entire 3-4 lbs because they tasted vile.
You may be more disciplined than me and be able to regularly drink protein shakes regardless of flavor but if you can afford it, do yourself a favor and shop around for a flavor you like. Protein powder is ultimately just a supplement, but it's also sort of food. You wouldn't really shop around for the cheapest fast food burger per ounce, you'd probably just pick the one you like.
Personal brands I like:
ON (probably one of the most popular consumer brands) chocolate is pretty good
Ghost Whey is pretty good for cookie flavors, but pretty expensive for what you get,
Dymatize Gourmet Chocolate is a recent one that I liked.
Out of this list from OP, for most people I'd say just get the Dymatize and call it a day.
