AmCare Woman & Child or Beijing United Hospital

Does anybody know which one better for ObGyn, AmCare Woman & Child Hospital or Beijing United Family Hospital ? My insurance covers both of them, so price is not the issue and as for the location both hospitals are close to each other.
I also heard that as from this June Beijing United Family Hospital has expat ObGyn specialist who speak english, german and swedish.

Does anybody can share their experience on these hospitals ?

Thanks in advance.
