Who would you say were the top Managers in The NWA/WCW, AWA, WCCW?

Paul Heyman was in all companies right? The best from World Class was obviously Sheik Skandor Akbar and Gary Hart. Jim Cornette and JJ Dillion were the best in NWA and special mention to Paul Jones. As for AWA well let's say that Dallas Diamond Page was great during the ESPN era.
