If you're in the U.S. and you use formula, due to FDA regulations there's almost no difference between the pricier "name" brands and store generics. Target, Sam's, and Costco house brands are all fine and much cheaper: https://thewirecutter.com/reviews/best-baby-formula/
Also: unless your Dr. specifically tells you to, there's no reason to use "sensitive" formulations. In fact, if you're also using breast milk, traditional formula may be easier on the baby because it's closer in composition.
If you *do* think your baby's a little fussy (defined as crying for no reason for extended periods) especially in the early weeks/months and you think it's due to digestion, one thing is proven to help in randomized controlled trials: probiotic solution. It's a little expensive, but widely available (even Gerber makes it). Basically it's a liquid that you can give them in small daily doses w/ feedings which will develop their gut fauna (since they're born with none) and will help with digestion.
The RD teaching one of my classes talked about a previous job developing formula. He mentioned that baby digestive enzymes are geared specifically for SN2-palmitate, but while all formulas include palmitic acid, most don't have that specific triglyceride and can be tough to digest.
