Of those 4, I'd say either Benn or Calzaghe (though Calzaghe was never a middleweight, at least certainly not at championship level).
None of the 4 would come close to Hagler, Leonard, Duran, Hopkins or Hearns at their peaks though (that said though, Duran's peak was probably at welter).
For sheer one punch KO power though, none of the above comes anywhere close to Julian 'The Hawk' Jackson.
