Formula for babies that spit up a lot????

My 3 month old has spit up since day 1. We were breastfeeding, but unfortunately, it didn't work for her, plus it made her spit up even worse than formula. We are currently using Enfamil for spit up formula. So far of the Enfamil line it works best, but she still spits up....a lot. I also recently started her on probiotic drops. Anyone else with this problem have a different brand of formula that has helped?
