Best bottles for formula

My LO is formula fed and been using tommee tippee for the past few months but LO started falling asleep after a few minutes of eating I decided to change the nipple flow to a medium flow but the flow was way to fast for him since he kept spilling the milk from the sides and gulping. I’ve tried dr brown but he didn’t seem to like it :( I don’t know what to do!
