Heresy to aerosexuals, I'm sure, but they're all just big tubes with wings, right? On the ground the A380s are clearly much bigger, but in the air they're fairly indistinguishable from any large passenger plane that isn't a 747.
They are significantly quieter than some, though. And the more capacious they get the less need there is for a third runway at Heathrow. (Disclaimer: blatant NIMBY.)
