Which formula works best for gassy and fussy babies ?

Initially I gave her similac pro 360 total care which is what the hospital gave her but we switched after 1 day because the formula did not agree with her . At my visit with the pediatrician 24 hours after being discharged they switched her to enfamil gentleease neuro pro in which I saw a difference but then when I brought her to her follow up she was still fussy and when she pooped the doctor said her poop shouldn't smell so bad and strong so we switched her to enfamil sensitive but still fussy and gassy , I'm debating if I should go back to gentleease as I feel the sensitive is making her constipated.
