the one that I've found is closest to the Primal spirit is Sun Warrior Warrior Blend Raw Vegan Protein. The worst thing in it is pea protein. It has coconut oil, is made with stevia, and the flavor is decent. However, the texture tends to be like choking on a sand bar (it gets better if you let it sit a while after mixing, but who wants to wait?)
another one I've come to appreciate is Jay Robb and Vega Sport
ETA: if you want to go strictly for hard-to-beat taste, low carb, high protein, my vote is for Isopure Zero. That stuff is delicious, but definitely not Primal.
