Midwife or OBYGN

I recently got to know that we can get midwife as an option in Canada, all covered by health care system. Lot of people say midwife is a best option if you are looking for natural birth. Would love to see if anyone has experience with midwife and OBYGN. What do you recommended. I got two options for midwife to select from. What questions do you ask and what you look for? I am 29 weeks pregnant.
