As an engineer I agree with "haughtney1" and "pakeha-boy".
The boeing product is better built but the BUSes are Job security for us engineering types.
Some of the MEL s on the bus create some interesting scenarios and ECAM messages accosiated with dead LGCIUs, EIVMUs Pacs etc would make you think the aircraft was AOG at first glance but the "clear" button and talking to the tech crew with a straight face seems to fix all that !
Merry Christmas
