Currently it would be Calzaghe by a fair way, with Haye and Hatton behind but also elite. Then the second tier would be guys like Witter followed by Froch, whos potential is yet unfulfilled and certainly unproven All-time you'd be looking at Jimmy Wilde, Ted 'Kid' Lewis, Jim Driscoll, Ken Buchanan, and Freddie Welsh. I would argue Fitzsimmons is probably best of the lost, but by your criteria he wouldn't count...
