What exactly was that experience? How did you make this determination?
Not accurate - they are newer than Boing AC. Many/most of the 767s are >30 years old and rollaboards were not as popular so the cabins look bleak and unaccommodating.
But the Boeings are better engineered and manufactured, and due to their age have better safety records.
I like the Airbusses as they are newer and have more + better creature comforts. So I suppose what matters most, design-wise, is if you get there.
