Who's a better all round fighter, Pacquao or Calzaghe?

I can't believe this would even be a discussion point. 1 guy has moved up many, many divisions thus far, taking on tremendous challenges every step of the way. The other guy stayed in 1 lacking division, defending 1 marginal belt for years before finally unifying and stepping up for some serious challenges. The only thing Calzaghe has over Pacquiao is the '0' and that is more by circumstance and design than anything else.
