There isn't. Meaning no matter WHAT formula, it will be TERRIBLE for one kid, and absolutely fantastic for another. It's trial and error. Most hospitals start with either Similac or Enfamil... but even then, there are half a dozen TYPES of similar or enfamil. It's a trial and error process. They're all quite different from each other. Each formula is stringently tested by the FDA and has the same minimum igredients (aka x amount of calcium, y amount of lipids)... but how they go about (aka sources) getting the nutrients into it AND how broken down they are reeeeeeeeally varies.
THAT SAID
The vast majority of infants do FAR better on 'premixed' of whatever brand than powdered. If your kid doesn't get gassy, constipated, projectile vomit, etc on powdered, count your lucky stars, because premixed (silky texture) is expensive as all get out.
((And ignore anyone who says the best formula is breast milk -because you know it will get said. Milk is NOT always best, despite what the catchy little phrase says. Mom can be adopting, taking meds, undergoing chemo or radiation, have structural issues, etc., etc., etc., etc., etc. -I can list 2 dozen reasons to avoid breastmilk like the plague just off the top of my head, although I'm definitely a proponent of nursing, it is NOT best in all cases. And baby can have numerous issues with breast milk including allergies and intolerances just to start an almost equally long list.))
