Legion Whey+ vs Optimum Nutrition Gold Standard
ON is cheaper per serving and has more protein per serving. Legion is a pure isolate with no artificial sweeteners. Which one you should buy depends on one question.
Optimum Nutrition wins on price and on protein per serving. Legion wins on what is in the tub and what is left out of it. Neither is a bad product, and anyone telling you one of them is a scam is selling you the other.

Where the competitor wins
ON is 17% cheaper per serving and gives you 2 g more protein in each one. It is also manufactured in facilities certified by LGC Informed Choice and NSF, which is a serious credential and not a marketing badge. If cost per gram of protein is your deciding number, this comparison is already over and ON wins it.

Where Legion wins
Legion is a single-source whey isolate. Gold Standard is a blend, which is why the protein per scoop is high relative to the scoop weight. Legion also uses no artificial sweeteners, which matters to some people and to nobody else. If you want to know exactly what protein you are drinking, the isolate is the simpler answer.
The number most comparisons skip
Almost every 'best whey' list compares protein per scoop. That flatters blends, because a blend can pack a bigger scoop. The number that decides value is cost per gram of protein, and on that measure Gold Standard is ahead: roughly 7.5 cents per gram against 9.9 for Legion. We publish that even though we earn a commission on one of them and nothing on the other.
So why would anyone pay more
Because a blend and an isolate are not the same product. An isolate is filtered further, which removes most of the lactose and most of the fat. If whey has ever sat badly with you, that difference is the whole reason to pay it. If it never has, you are paying for a filtration step you do not need.
What neither of them is
Neither is a shortcut. Total daily protein is what drives the result, and powder is a convenient way to hit it, not a superior one. Chicken, eggs and Greek yoghurt do the same job for less money per gram. Buy powder because it is easier to reach your number, not because it works better than food.
Who each one is for
- Cost per gram of protein is your deciding number
- You want the biggest tub for the money
- Whey has never caused you any digestive trouble
- Whey has sat badly with you before
- You want an isolate rather than a blend
- You avoid artificial sweeteners
