There is no perfect food, and a food that works well for one dog may not work for another, so the best you can do is choose a maintenance diet from an established company (one with veterinary nutritionists on staff to oversee formulation and quality control) and then monitor important signs, such as weight, stool quality, coat quality, etc. There are many good choices and only a few I would recommend against (raw diets, and BEG diets).

Hope this helps!

PS: I mix foods all the time, I can’t afford to throw out good food.
