Best food recommended by veterinarians?

First off, I know Purina, The Hills, Royal Canin are the main brands recommended by veterinarians but say I buy my cat Purina so I buy her Purina Pro Plan or Purina One? Which one of these is the one vets recommend? I’ll be feeding a combination of wet and dry food so for breakfast wet food, for lunch dry food, for dinner wet food and any time she uses her puzzle feeders I’ll use the dry food. Is this a good combination? Also what flavors should I get? Just the chicken one?
