NOD, FC & IcePack,

DISCLAIMER - this is not to set off any A-vs-B arguments - it is just a bona fide question.

Right...

Let's consider 2 aircraft of the same type; one a/c has full Airbus-style FBW, the other has Boeing controls. All other things are equal and weights / speeds have been correctly determined and entered.

Both aircraft rotate simultaneously on parallel runways and, after the main wheels leave the concrete, are both simultaneously subject to a force which, all other things equal, would tend to cause an over-rotation.

Under 'normal' law, would the Airbus-FBW-equipped aircraft be more or less likely to strike its tail, compared to the Boeing?

The logic I'm using is this: should A's FBW computers be able to detect the nose-up force quickly enough and reduce the control surface input quickly enough to prevent a strike?
