i don't sincerely know who would win this fight,crazy diamond has a very great physical strenght and speed,gold experience has average strenght and great speed.......Crazy diamond power is to restore things to their original form or in a different form "like the nose of that school thug who messed up with josuke's hairstyle XD". Giorno,in the other part...has the power to:
-Accelerating senses of the opponent
-reflecting damage "wich would be very useful in such a fight"
-creating body parts "wich is a bit weaker respect to josuke's healing ability"
To me,this would be a pretty intresting fight to see,after all giorno is very smart and i'm sure he would not let josuke defeat him that easily.
