All the names you mentioned are all very good foods.
I tried Flint River Ranch since my friend swears by it.
(It's a human grade baked kibble)
My dogs gulped it down for the first 2 months and
grew quickly tired of it. I than tried Innova and
used Innova for about a year till I learned about
Canidae, which is also a human grade product.
I started mixing the Canidae with the Innova,
since the Canidae is cheaper in cost.
The dogs loved the Canidae.
After about 6 months I did away with the Innova and
the dogs have been on Canidae ever since.

The dogs never lost interested in the Canidae, and are
doing well on it. Sheba skin is dryer with the Canidae
but she is also a senior. I add a couple squirts of
linatone etc. to make sure they get enough
oil. (I also add human food)

I personally would stick to the Nutro if Nebo is doing well on it.
Nutro is a good food, but not human grade.
Sheba was on Nutro for 5 years and she did fantastic on it. Rocky did not do as well (sensitive stomach) and that is the only reason I switched to a human grade food.
