Best formula for fussiness and gas?

A❤️C

My baby is 7 weeks old. He first started getting really fussy with breast milk (I exclusively pump) to the point I've almost stopped giving it to him and now recently it happens with the formula too. I use enfamil neuropro. Any recommendations for formula for the best price for gas and fussiness? I was using the store brand neuropro for best price wise.
