I'd always give birth near medical help if possible - as said, things can unexpectedly go wrong, and while the chances are very small if everything looks ok, any chance of something terrible happening is not a risk I'm willing to take.
My uncle is severely brain damaged due to being born with the umbilical cord wrapped around his neck and being deprived of oxygen for too long. It was my grandmothers 5th child, so she was deemed very low risk having had 4 normal labours/births etc. So personal family experience on how it can all go wrong :(
Wish there were nice birthing centres available that had full operating suites as part of them - that would be the best option in my view to have a retirement village type setup with nice rooms/gardens, with the medical stuff right on hand if things go south...
