The original stunner, viewing wise looked more damaging, but it got quicker and more from out of nowhere shocking and the opponents selling of it got more and more over the top (
The Rock's was best or worst depending on how you look at it)
Check out the
Austin stunner in this package....
I think what worked for it was the boom, out of nowhere he hits it, a lot of finishers need a full on set-up, thats what made the
Diamond Cutter such a hit in WCW, from the samoan drop/fireman carry's position, off the middle rope, face to face, powerbomb into one, chokeslam into one, heck he reversed a jackhammer into it on
Goldberg, to do the whole "Is it really damaging", fans now are more concerned with does it look cool

What I've hated recently are
Melina and
Mickie James' moves, especially Mickie James jumping DDT where its beyond obvious, to the point you can't suspend disbelief, that her opponent is assisting with the move.
