Our take
Blue Buffalo hits the sweet spot between quality and cost. It's not as scientifically rigorous as Purina Pro Plan or Hill's, but for owners who want better-than-supermarket ingredients without a subscription or premium price, it's a solid pick.
Hill's Science Diet is the rare budget-friendly pick that doesn't compromise on science. It's vet-recommended, widely available, and has a senior formula that's hard to beat at this price point.
