I currently use Canidae and found it to work the best for me and mine, but I also use raw. I use ground turkey, turkey necks and chicken quarters. Nupro is my supplement of choice. I have used Innova on young dogs, because their metabolic rate is so much higher and works well to help maintain and get weight on. I would not use it for those "easy keepers". But I do see now that they have a large breed formula and has had a senior variety. If i were to get a young dog again, Innova would be my choice and for the matured out, not senior, I use the Canidae. Nutro gave my dogs all "Montezuma's revenge!" Didn't matter the bloodline, age of dog, country of origin or formula. I am sure there are plenty of decent kibbles out there. I never used Diamond. Thought about trying it once. Got to see what works for you and yours in the long run.
