I feed my Puff Kirkland C&R (available only at COSTCOs, made by the same people who make Diamond and Diamond Naturals which are available at many feed stores).* Kirkland C&R is about $15 + Tax for a 40 lb. bag; Diamond Naturals, which is very close to the Kirkland, is a few dollars higher.
Of the foods you listed, Eukanuba and Purina's ProPlan would also be quality foods but I think the Euk may have a few more grains and fillers. Iams is a cheaper version of Eukanuba with more grains and fillers.
IF you're feeding a puppy 6 months old or less, IMO it should be fed a Large Breed Puppy food.

Bess [BF, AKC bench line (from competing show breeder) 55 lbs., 1967-1981] "Poor Bess, the Wonder Dog":
I voted other. We use a local brand developed by a vet around our area. It contains flaxseed and omega 3 among other goodies. It is a more dense dog food with less air and requires less per feeding. Our breeder uses it and has been breeding for over 10 years successfully and it is also recommended by our vet as well. Plus it is less expensive then Science Diet and others you buy at the pet store. A bonus for our budget.
Other also. We feed Nutrisouce.
Purina Pro Plan
Daimond Naturals. No corn or fillers.
Other; Kirkland which is made by Diamond. I've also fed ProPlan.
Nutro Natural Choice Lamb and Rice
I voted other, Natural Balance
