It is hard to compare but I still give a slight edge to Jordan but Lebron is #2. Lebron to me is a modern day Wilt. He is just a physical and athletic freak. Also a freak in terms of his health.
LeBron is more than just an athletic freak, he's also one of the greatest passers of all-time, can score at will, and could shut down anyone in his prime (when locked in).
