I always preferred the Airbus to the Boeing planes. The foot cutouts, the fact that the planes are newer, and the video screens always made for a nicer flight.
The Airbus planes are also quieter and I agree that the seats seem more comfortable.
So, in short...
What gleff said
EDIT to distance myself from gleff's 9C comments. I would never book row 8 or 9 on the 757. I hate any kind of bulkhead seat because they don't offer storage. Row 9 on the Right side is even worse as it's one of those tricky exit rows w/reduced seat width w/o increased legroom. (9F is the worst because you think you'll get extra legroom, but your feet are squeezed by the slide, and you still lose storage!). HATED... HATED seats!
