Crash happens, and gas pedal or linkage is damaged so as to cause the engine to run/race wide open.
Which one is more likely to shut off the electric fuel pump?
I have witnessed two accidents like this, but neither of the vehicles involved had electric fuel pumps.

On most of the modern cars I have been around both are used (inertia switch and oil pressure switch). I use both, but if you were only going to use one, I would go with the inertia switch.
