Nope.

AC can induce muscle tetanus, but while it can cause you to lock a hand to something, DC is quite a bit more likely to do so. AC has a greater chance of causing a spasm that either removes the hand or allows the victim to pull free.

AC, however, is more likely to kill you, as it can trigger ventricular fibrillation. DC is more likely to stop your heart, which can actually be easier to recover from.

As for Edison, he electrocuted the elephant and invented the electric chair to illustrate the dangers of AC current. Not because he thought it would be all that dangerous at household voltages, but because he owned the patents on DC and wanted AC to look bad. Look into Edison a bit, you will see that he was something of a jerk.

However, for local grid purposes, AC is much better and won out in the end.
