Lebron is by far the most aggressive and intense player in the league right now. I kind of doubt that Durant will ever reach a higher level of ability than Lebron.
I think Durant's defensive skills are very much inferior to LeBron's, although I will say that I feel like sometimes LeBron also doesn't try as hard as he should defensively. LeBron also seems to have superior team leadership skills to Durant. Teammates seem to naturally follow LeBron's lead. Some star players just don't have the same team leadership qualities that other players naturally do. This can make a big difference in rallying your teammates during clutch moments when games are close and likely to go down to the buzzer.
Lebron with no question. I really thought KD was closing the gap but LeBron's over all brute force and strength just catapults him to the top. He's now added a post up to his repertoire and his shooting has improved a lot too. He is a better play maker as well and his court vision seems to be superior.
Grand opening was pushed back once again, we'll just say it's TBA for now. We are still waiting on the completion of some custom development that has been in the works.
