Well a couple of points - First Class on the A380 was good, the showers were a gimmick that I never bothered with. But First Class on all major airlines is good - the only thing that made EK's First Class stand out was the individual cabins and they have those on the 777. The bar area was good but they were not the first airline to have a bar, Imperial Airlines had one in the 1930's.
The A380 didnt have anything that other airlines or aircraft types had - that is why compared with Concorde (or the 747) it was not a revolution, or even evolution, in air travel.
