Our read

Nearly identical brand-trust and ingredient-clarity profiles, so in our view this comes down to nutrition fit and price: Hill's posts the stronger nutrition profile, and while neither food is cheap per 1,000 kcal, Royal Canin's value score lands at the bottom of the range we score.

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.
