You cannot fault the Emirates Suites on the A380. There is a pretty good write up of the experience in the link here, although the turbulence meant no showers were used.

However, I am also a fan of EK's business class. I may get the chance to try it between SYD-AKL next year. They have a very good product, and it is much cheaper than the equivalent of EY or TK.
