SQ772, I'd however have to agree with 9V-SVE on some points.
The First Class that i've tried and are still in service are the ones on the SQ B744s, the 12 seat skysuites and 16 seat normal first, SQ772 and 773, with normal 2-2-2 First Class seats. Yes, as you said just like the A340, the normal first class seats are also very comfortable! However, comparing to the skysuites, i'd say that only the skysuites really make you feel like flying first, when the skysuites exsist. Totally privacy, a absolutely different seat different features on the seat for example 14 inches screen monitor, a fully flat bed etc. I'm not too sure about the A340 First, however the B772 and B773 first seats could not be reclined to 180 degrees, on the normal first class seats on the B744 the seats could reach around 170 degrees of recline, not yet totally flat though.
Just take this as an example. Some businessman is paying around $6000 US dollars to fly on SQ first from SIN - SYD. However as we all know that sometimes SQ send the 16 F configuration to Sydney. And so he got the 16 F configuration B744s. On his return flight, he got the skysuites B744. If you were him, well you (at lease me) would ask the staff "Was I flying business on my SIN - SYD sector trip? Not really a joke, i'm sure that if the businessmen are expecting to get the skysuites but instead the got the normal first class, I reckon they won't be really pleased, especially he has to pay the ticket.
It's indeed two different thing when you fly the skysuite and the normal F. It's not just the seats that make everything changed, it's actually the atmosphere. I doubt there would be a great decline in service when you fly the normal F instead of the skysuites, still...when comparing, you'll get what i mean.

To be honest, if you've never seen both pictures and the remarks could you reckon easily which one is first or business by looking at the pic? I reckon the main difference between the two pics is that the the legroom on the A340 F is much much better than Raffles on the A340, just like the pic below.

When you compare both pictures, you'll see what i mean. Also a 2-1-2 configuration in F.
SQ should not bother to install Skysuites and Spacebed on the B772 and B773 in my opinion, especially when the B773 are also used for medium - long range destinations, along with the B772. It's understandable that SQ does not install them on the A310 and A340, however for the rest of the planes......
