Both are equally good. I am on subsidy route for two pregnancy. My #1 was at NUH while my #2 was at KKH. I would say depend on individual experience. Both are equally good and have great nurses and doctors even midwives. While most of them mentioned at KKH they had bad experience, I had a positive experience. However the only thing I would feel could be better would be the stitching on the slight tearing I had. In KKH, the stitching part wasn't good and neatly done as compared to NUH. That was the only thing that I would give negative feedback. But service wise both are good.
