Formula recommendations?

My son has only been on only formula a little over a month. I was pumping before but just couldn't sustain pumping when I went back to work. He never spit up with breastmilk and was not fussy. We used regular yellow can enfamil to supplement with so we continued after. But his spitting up seemed so bad, he's burping SO much and spitting up so much every time he burps. He's also pretty fussy. I did enfamil gentlease for a couple of days, didn't notice a change. Went to similac sensitive for a week (this is what my first used with no problems) and still nothing is getting better. Might actually seem worse.

Anyone have a baby that spit up a lot, was gassy, and fussy... what formula helped?
