Similac total comfort reviews ?

Hi all my baby has been gassy and fussy. He is only happy with gas drops so my doctor finally changed his formula to similac total comfort. I was just looking for some reviews on this and what anyone thinks of it if they have used it to for gas and also poop issues like watery poop and infrequent. Also any other comparison brands ppl used would be helpful in case this doesn't work for us. Thanks
