Is blue buffalo wilderness a top quality brand?

So I have a question. Ive been working my of this week (3 days straight) to get my dog Hannibal really good quality food. So I went to the pet store and bought Blue wilderness because I've heard some good thing about blue. So is blue wilderness up their with pure gold, Timber wolf, wellness etc. I just want to hear from a pet owner point of you not some website tailored to make the pet food look "healthy" so I went to the pet store I was about to get science diet unknowing how bad it was. but instead I got blue because its based on what dogs ate thousand of years ago. And its grain free. Ive also heard wilderness is their best blue Buffalo product. I went on the web to today and searched for reviews some say its excellent some say its decent. Was it worth my money? Should I work my of to get my pet good food? If you didn't know I'm a kid. Will wilderness give my dog what he needs ? The bag says at his age he only needs to be fed 2 times a day about 3 cups each serving which is good. Anyway straight to the point I wanted to get quality food for my pet is it quality?
