A genuine upset: the mid-tier Purina ONE outscores vet-channel Hill's Science Diet on our rubric, tying it on nutrition fit and leading on sensitivity risk and value, where Hill's price per 1,000 kcal drags it down. Hill's answers with a clearly cleaner ingredient panel and a hair more brand-trust signal. In our view the cheaper bag is the better rubric outcome here.
This verdict is our opinion under the PetScored rubric, not veterinary advice. The exact sub-scores are in the table below; each food’s source confidence and limitations stay on its own scorecard.

Purina ONE
