Eh, I have a different experience. The A380 porpoises on autopilot cruise, alternating between lifting you slightly, and settling slightly. The regular drop induces a startle reflex that makes it really hard to sleep. My favorite plane for long distance is the 787. The mechanical bits are pretty noisy on climb out, but when cruising it's a really comfortable ride.
