Can a formula make baby less fussy?

I’ve been using Earths Best Organic Formula for five weeks and my baby was doing great! I didn’t have any other baby to compare him to but he is growing strong and healthy. I switched to Holle for 24 hours and he wasn’t nearly as fussy and didn’t root as much and slept longer! He did however go from a poop after each feeding to 2 poops a day. My pediatrician said to stick with earths organic if it is working for him because Holle is from Germany and we Won’t know if there’s recall. I would be concerned about not getting recall info. I switched back to earths organic and my baby is hungrier, roots like crazy and is fussier 😞 what do I do? It could be a growth spurt or the formula?
