I can add from a pax perspective with many gold for life accounts with a few airlines..I avoid the 777 where possible due to the loudness of the cabin and air quality. The second planes I avoid is 767 and 744 in that order. My fav aircraft is the A346 up front smooth and quiet as is the 330. A380 is just a delight for a passenger.
It's not all about the bean counters and pilots. Airbus planes are much more pax friendly I'd have to say.
My 2 cents
