Re: "From my experience (Emirates), I'd rather fly A380 than B777"
Agree. I flew Singapore to Heathrow on business class on the 777, and it's terrible. The "leg hole cubby" area is not straight ahead of the seat, so you sleep or lounge at an angle, whereas on the Emirates business class 777, it's straight ahead and more cleverly configured.
But I also agree with the other points. The A380 is smoother, quieter and therefore more comfortable, all other things considered.
