Bottle recommendations?

My baby will be one week tomorrow and he is formula fed. We are currently using Dr Brown's options bottles with level 1 nipple but ive been noticing that when he drinks hes making huge gulping sounds and milk leaks out the side of his mouth. He has been passing alot of gass as well. Hes constantly farting. I don't remember my tott farting as much. I bought Tommy tippy bottles with the straw so hope they work out. Also he making a gagging face because the nipple is too long. Any bottle recommendations?
