Wow, that list contains 4 of the worst (in my opinion). Wasteland is a pathetic excuse for a finisher. World's Strongest Slam is weak. Skull Crushing Finale is like many other finisher's I've seen. and The Cross Armbreaker is the same move that countless "technical" wrestlers have used for years.
Not that anyone asked, but this would be my 5 (in no particular order)
RKO (with the wake up taunt)
Killswitch (or as I still call it, Unprettier. why did he change the name of it?)
Kane's Chokeslam (with wake up taunt)
Pedigree
Sweet Chin Music
Not to get too technical, but it didn't start as the Unprettier, either. When he was with the Brood, it was called the Impaler.
