Del Piero is absolute class, probably the nicest man you could meet in football, as humble as they come.
But more talented? Come on, lets not mince words, Baggio was superior by far, ask any non Juventini who was better between the pair & most people would instantly say Baggio. As he said himself, everything he done in the game he did with one and a half legs.
If you are old enough to have seen all four of them play (don't know why Pirlo is on that list though), you would know why Baggio was better. When Serie A was the greatest and most competitive league in the history of football, Baggio was tearing teams apart, for fun. Scoring mind boggling goals from every angle on the pitch, as everyone knows he dragged a mundane Italy side to the final of the 1994 World Cup, which neither DP or Totti ever did.
