Titanium, et al, a list of technical issues is of little value without context.
In the Airbus-Boeing environment there are significant differences in timescale and thus available technologies; also differences in philosophy, yet both achieving the objective of improving safety.
There are also differences in design philosophy and marketing strategy; Airbus in their time, highly innovative, Boeing less so, and chose not to follow the Airbus route, yet both have been successful in safety and conversely in suffering problems of human interface.
Other differences might account for this, designs not matched to the current operational environment, inappropriate assumptions about who and how the equipment will be operated, or did not see the new range of social influences on the human.
Thus a change between aircraft types involves more than equipment or systems functioning, it has to consider deep seated reasons and assumptions about the aircraft design, the operational environment, basic training, operator expectation and individual adaptability.
Yet at the end of the day, they are all aircraft, to be flown, operated, and enjoyed; the technicalities are not as important as is the way in which we think about them.
