The TAM 320 wasn't caused by anything other than bizarre thrust lever handling, I don't see how you can pin that accident on airbus design philosophy. Thrust lever movement and "conventional" control yoke feedback didn't save the THY crew at AMS. We could compare Boeing and Airbus crashes all day and call it a dead heat, as has been mentioned Human Factors have more of an impact on the incidents you mention than aircraft/flight control design philosophy. That was certainly the case with the report above.
