Which aircraft has a most strength in stresses and can be abused..? Boeing or Airbus?

the useful life of a Boeing aircraft is longer than a Airbus so I would think that a Boeing would take more stress. Tex Johnson did a roll in a 707. a good pilot can do alot of maneuvers and not stress. the aircraft. have you seen any film of how BOB HOOVER. he could do all kind of maneuver. he could do rolls ,loops with a gl of water and not spill any during the maneuver.
