Similac total comfort vs Enfamil Gentlease

Help a momma out! My son is currently on Similac sensitive but he’s been gassy, fussy, & spitting it up a lot lately so I’m now looking to switch his formula again.

I have wic so staying with Similac would be ideal, but I’m also willing to pay out of pocket for Enfamil if it is truly better.

I understand every baby is different but I also want factual opinions.

I’ve bought both to try out just in case the total comfort doesn’t work.

And yes, I’m aware I should consult my pediatrician, but I’d also like to solve this on my own before going to my sons two month check up the 2nd week of July.
