Must be me, I see a lot of people enthusing over the comfort in an A380 but it was something that never struck me as head and shoulders above the competition. Yes it was a bit quieter but when you are watching a movie wearing noise cancelling headphones it was just the same - and you still need noise cancelling headphones on the 380.
Also at lot of passenger comfort is down to how the individual airline configures their cabin. I only flew on the 380 once in Economy and it was easily one of the most uncomfortable flights I have had - but I suspect that was down to it being BA rather than anything to do with the aircraft.
