Large breed puppy food comparison?

This is almost a dead heat. Very little difference. Same Omega 6 to Omega 3 ratio. BB has 2% more protein, Very little difference in fat, fiber, moisture, calcium/phosphorous ratio. Both have chelated minerals. Both use whole grains. Ingredients are almost identical. Wellness has some fish. I like the life source bits in Blue Buffalo and it is about ten dollars cheaper for 30 pounds.
