Possibly the most successful maneuver in terms of number of people who have kicked out of it if we take Hogan's usage into consideration, it is one of the simpler maneuvers where the size of the opponent does not matter.
Though it has been used as a mid match move for a very long time with not even a pin attempt following it, Hogan, made this move famous by using it as a finisher.
There are lot of variations based on where, how and what you do before using the move which is signatory for the wrestler like say the double leg drop of Kofi Kingston or Guillotine leg drop of Undertaker or bulldog leg drop of Kelly Kelly and Melina (reverse of it).
Is Hogan's Running Leg drop the most successful maneuver in terms of kick out ratio and how do you take it as a finisher?
Don't fear the axe, fear the man holding it!
