I haven't looked too deep into it because I don't plan on having children, but it's probably cheaper to have the kid at home. I've met a couple people who opted for the home birth and they were glad they did.

(I've also just personally always thought giving birth in the bath with water would be the way to go if I ever did it. Feelings that it might be easier for baby to be born into water and not directly into cold air after being in the warm amniotic fluid so long.)
