so far in my F experience I think SQ comes second after EY... even SQ it was not A380, I cannot imagine those suites it must be outstanding.
I'm not a fan of the SQ A380 cabins. The 'privacy' which you see on the website and brochures is not actually there. Also I object to having to get out of the seat to turn the whole thing into a bed. Finally I felt the video resolution of the IFE was pretty poor considering the screen size.
Having said all of the above, I do like the SQ service.
When the seat gremlins are not playing, I actually prefer the QF A380 F seat and cabin. I am however keen to try EK, although I would prefer not to give my cold hard cash across to them.
