What is a good brand of dog food?

Is there any proof that brands like Blue Buffalo or Inova are really any better for my dog? I want the best for him but I want him to like his food. I got him blue buffalo he reluctantly eats it but looks at me like i am retarded every time he takes a bite. After a month his skin and coat do look better and he doesn't fart as much but I can tell he hates the taste. Purina 1 is his favorite but propaganda has lead me to believe it is not good for him. (at least as advertised) So is there any merit to holistic natural dog food claims? If so what is a good brand?
