Here is my top 4 well top 5
1) Chris Paul (overall which includes passing, shooting, iq with an ok defense repetoire)
2) Tony Parker (isn't as good as paul knowing how to orchastrate the offense but can shoot better than most think, a champion, and clutch 4th quarter player)
3) Rondo/Harris (even though i love rondo , harris is definitely his equal in terms of everything plus he can shoot better at this point with rondo being a better defender. (though harris is better than most pgs still in the nba)
4) Deron Williams (rondo has smoked him almost everytime they have played. His offense is complete but his defense is too average)
5) Chauncy Billups (not a natural pg but has become a really good pg with experience, average defense like williams)
Now by categories amongst these 5 pg(no particular order)
best shooting pgs = Paul, williams, billups(
best posting up pgs = williams, billups
best penetrating pg = (honestly all are good)
best drive and dish pg = Rondo, Paul
best defensive pg = rondo
best clutch pg = parker, billups
