Guys, Girls:
I think we have to be very careful about accidentally comparing apples to oranges here in this discussion.
The performance rules, certification basis, operational practices, etc. between Part 23 aircraft (generally the 12,500 pound and under crowd, although there are a few derivatives of smaller planes that are heavier than 12,500 in that group) and Part 25 aircraft (Boeing, Airbus, etc.) differ greatly.
