Don't know enough about Airbus, but I saw Boeing build the 767 prototype and played around with the mockups and did the engineering familiarisation course.
Boeing builds a very nice aircraft in my opinion, at least from the maintainability point of view. They also listened to their customers (in those days).
Douglas on the other hand built over designed aircraft and and anytime you offered a suggestion all you got told was "We built the DC3, when we want your opinion we'll ask for it."
Typical example - pilot's opening window on DC9 - finely machined castings and forgings, lots of levers and a spring. Boeings one looked like it was cobbled together from old tuna cans.
