Delivery, baby care and child education are the costliest affairs in Bangalore right now... so it all depends on your budget.. A child delivery package right now can cost you anywhere between 80k to 2 Lakhs depending on the hospital and the package that you choose.
To answer your question, Motherhood is trending and the considered the best hospital for delivery right now. They have many branches in Bangalore, mysore road too. .. and they have assembled the best gynaec doctors there... 90% of the doctors are women...
Both my sisters delivered their kids at motherhood. Email me on firstname.lastname@example.org if you need all the package details and the doctors who cared.
Cloud9 and The Nest are other good options... If you are looking for a normal delivery then St.Marthas is the best one you need consider.
Not an expert on the subject... I replied only to keep your thread alive.. Lets see if others reply now.:P
