I like the teat on these, very soft and mimics the breast when it's in the babies mouth better than mam. Mam bottles are also 6 parts to clean and sterilise which is double these ones!
We have used both! Loved NUK but the flow on teat 1 was way too fast for our son, so he was on MAM with teat size 0. Don’t get too many of one brand and try them out to see which one your baby likes 🙏
Nuk is easier to clean
