I do give the edge to the 1996, and probably 1984.
In 1996 you have 3 MVPs (Iverson, Nash, and Bean Bryant) along with Ray Allen, Marbury, Walker, Abdur-Rahim, O'neal, and Stojkvoic which were all all-stars. Plus Camby's been very solid for years.
I do think top to bottom, at least in the last 20 years, the 1996 draft was the best.
