Getting out of a serious situation.
Unfortunatly that is a question that no one can answer as it depends on the situation that you are talking about.
The only thing I will say is that the Boeing non normal check list (QRH) is a a lot better to use, the Airbus paperwork can be troublesome at best, the electrical fire & smoke is a very poor joke that I think must have been written under the direction of lawyers.
What is clear is that both aircraft are very safe mechanically, both have there good and bad points the result of this is the only reason I would prefer to be in a Boeing when things go wrong is that the checklists are much more user friendly.
