I use the Avent bpa free ones and they work well. I have tried Born Free, but I found that the glass chiped on the neck of the bottle, so I threw them out and have not used them since.
I have only used Born Free because a friend recommended them and we've had no problems with them but again, they are the only ones we've tried. The reason my friend recommended them is because her BF baby would only use the preemie nipple and Born Free has that. That's also the nipple I use (even though neither of our babies were preemies) and it works good.
