to be honest, if you ask any paeds, they will say all milk formula are the same. They are required to meet the minimum requirements a baby needs. For the recent years, there have been hype about adding DHA/ARA and prebiotics/probiotics into the formula. If I am not wrong, all milk companies have added that into their formula. so now it depends on individual babies, some babies are more suited or prefer the taste of one type then the other. I would suggest you call their hotline to ask for samples before buying the actual size tin. Otherwise it will be a waste of money if your baby doesnt suit.
Companies like Nestle (NAN), Abbott (Similac) and Mead Johnson (Enfa) are pretty reputable, so should be fine
