Our verdict
A dead heat — buy on size and flavour
This is the first rivalry where the efficiency scores match exactly: 82/A apiece. And it gets better — protein per 100 kcal is identical too, 10.3g each. These two bars are, nutritionally, the same product in different clothes.
The difference is format philosophy: Fulfil gives you 14.4g protein in a 140-kcal bar with added vitamins; Barebells gives you 20.4g in a 198-kcal bar with a 94 Clean Score and a far bigger flavour range. Bigger hit vs lighter touch.
So there's no wrong answer — only a wrong expectation. Want the most protein in one sitting? Barebells. Want the lighter option? Fulfil. The labels refuse to separate them.
