if you can afford, of course c+ is better. but twins is high risk case, i suggest public hospital.
to me, i choose c+ 'cos I can choose who does c-section for me. dr. is the most important. i don't want to be a 'white-mouse' 'cos i had bad experience in public hospital (threatened abortion b4).
some of my friends went to public hospital and they said ok.
but most of my friends choose c+ cos they can afford.
