I chose the Tommee Tippy bottles because I thought they were closest to breast feeding, but they gave my little guy gas. We switched to the Similac Simply Smart, which have the tab inside for mixing formula and killing the air bubbles in there. (Tommee Tippy actually has ones designed for reducing gas, but the similac were much more budget friendly) But it was trial and error til we found them, just gotta find what works.
We didn't care for the Tommee Tippy bottles. I like the design of it because it looks to be more shaped like a breast, but the nipple collapses easily and i'd have to pull out the bottle and let it air back up several times during a feeding. The Similac Simply Smart bottles are really nice, we got a couple for free in the mail from being on the similac strong moms program. We primarily use Dr. Brown's bottles though. Lots of parts to the Dr. Brown's but we just love them. No bubbles at all.
