Would you rather get a Tombstone Piledriver off the top of the Cell or get an RKO off the top of the Cell?

RKO since if your in a Tombstone and you jump off the cell your head is at a greater risk of hitting the floor while when your in a RKO the only serious injury you might get are cracked ribs, dislocated shoulder or dislocated knees instead of a possible neck injury that leaves you paralyzed
