I see Lebron as more of an orchestrator, a next generation Magic Johnson with an explosive athletic ability, I can't compare Lebron with Jordan or Kobe cuz their games are different, Jordan is more of a scorer than a playmaker same with Kobe while James is more of a playmaker with insane hops.
In the long term, James might become the better player than Kobe but not by much, he just needs a better supporting cast in the comming years to reach the summit.
