From memory, does this have anything to do with the Airbus being able to fly at less than 1.3 Vs due its fly by wire technology/protection, and the boeing flying 1.3 or more on the approach to land. Both aircraft similar LND weight so could attribute the higher Airbus pitch. Also the Airbus only has single slotted fowlers, where as the boeing has tripple, this also may be why there is a difference in approach attitude.
