Where are you based in Singapore? I can recommend to you Dr Chris Ng, he's my gynae and obstetrician. He's really good. You can also consult him regarding fertility treatments if you're TTC :)
I'm not familiar with the two docs, but if you're considering going private, I would like to refer you to my obgyn. His name is Dr Christopher Ng and he was my gynae for my two pregnancies (both Csec). His stitches are neat and small. His clinic is at Camden Med if you're interested.
Wishing...
