Jordan > Lebron
Jordan may not have the physical attributes of Lebron, but he has the better winning mentality. Lebron has been to the finals 4 times, and brought home 2 rings. It would have been ONE ring save for Ray Allen's heroics in the final seconds of game 6 last year, following a missed 3 pointer by Lebron...
Jordan always found a way to win. Hence, 6 finals trips, 6 rings.
