Winner: It depends on your goal.
If you’re dairy-sensitive, vegan, or want whole-food greens along with your protein, Vega Premium Protein + Supergreens is the better fit and costs less per tub. If pure protein-per-dollar and fast post-workout muscle recovery is the priority, Optimum Nutrition’s Gold Standard Whey is the higher-scoring, best-selling pick.
