This is what I personally think of each player:

Kobe Bryant has better knowledge and skills (such as dribbling, shooting, etc.).

LeBron James has better athleticism, which really helps his defense (such as getting blocks) and allows him to run to the goal easier than others.

I would take LeBron James seeing that he's younger and more versatile. Kobe Bryant is great, but I think he's mostly limited to the shooting guard position while LeBron James can be a small forward, power forward, or possibly even a shooting guard.

The one reason I thought of picking Kobe Bryant is because of his adaptation of getting older. As LeBron James gets older, his athleticism will go as well. As a result, I would think LeBron James would have to increase his knowledge and skills (as Kobe Bryant seems to have done) in order to have the career people expect from him.
