Eh, both are solid hospitals la, tapi memang depends on your situation! Assunta has a very good reputation for obstetrics and a lot of mums swear by their gynae team, but Sunway is SO convenient kalau you're in PJ area, honestly, proximity matters when you're in labour, especially if anything urgent happens. A few of my mum friends chose Sunway purely because they didn't want the stress of a longer drive, and they were very happy with the care. For C-sec specifically, I'd suggest calling both hospitals' obstetric departments and ask about their C-sec rates, their package pricing (can be quite different!), and most importantly, which gynaes you trust and which ones are available at each hospital. Your comfort with your doctor is actually more important than the hospital itself, honestly.
