I don't know what your criteria is for Wade's best seasons shytting on Iverson's best seasons. Iverson averaged more pts, more assists, more steals, only .2 more TOs, shot better 3pt %, got to the line more and shot a better FT % for his career, and did it over a much longer period on worse teams with little to no support. Like I said it's up for debate, but Iverson's best seasons are better than Wade's best season and that's actually not up for debate.
Wade is def a better defender, team player, and a higher bball iq though.
