I didn't find SQ C to be that superior. The old seats on 747 are still not very spacious with limited seat pitch. Service was surprsingly good but that was only one flight so it was hardly conclusive. Food were good, but not exceptional. NH can give it a good match anyday.

Sometimes I even found SQ service in F can be very inconsistent. I was really sick on a flight from SIN to TPE in F [no it wasn't SARS, thank God], I just kept to myself but the attentive FA noticed I wasn't well. After the meal service, she would come by very often to provide hot towels, hot water and asking if I am feeling better. Then, another male FA would come over asking the same question - obviously, she told him. And it had nothing to do with SARS, wasn't like they were worried or something. On arrival, pretty much all the FA in the F cabin knew I wasn't well and all wished me getting well soon and suggested I rest. I thought that was very attentive and kind by showing they care. Then, on my flight from TPE to NRT again on SQ F, the service was more or less lukewarm. So on SQ, you really never what to expect in terms of service. Sometimes, you get excellent service, sometimes you get a robot.
