Out of your list, I would pick Prandelli or Spaletti.

It is all too easy to slate the coach when a team loses/drop points, but overall Didier has done a good job with the players he had. Yes, we've taken out our frustration of droping points out on him, but let's remember, Didier was the guy, who took on what looked, at the time, to be a really rotten job. Serie B minus 17 points, meant that our chances of getting back to serie A in a year was slim. However DD took it on & did so with a professional attitude, unlike Capello, who, despite having played for us in the past, bailed out like a rat deserting a sinking ship. IMHO DD was a true Juventino and came back to help us, just like Pavel, Gigi and Alex, who stayed to help us out. With less than eight weeks to go, Juve are looking good and serie A is getting closer. I love Lippi - he is my favorite manager and I'd love him back at Juventus, but not necessarily to replace DD.
