C-section might be easier at first, but the recovery can be painful. Also, depending on the situation, if you go Caesarian for the first time, you may have to do it every time (due to risk of rupturing the uterine lining on subsequent deliveries).
My wife had a C-section; the actual surgery went well, but it's taken about 9 months for her cut to fully recover.
You really need to talk to the various doctors a lot to understand why they recommend certain courses, and then figure out what seems best for your wife and you.
