LeBron.
As other posters have mentioned, he seems like a better teammate and an overall a better person in general, from what we see of him in the media. He seems like a very humble guy at times and I would bet that if you walked up to him in public asking for an autograph, you'd probably have a better chance of scoring one from him than Kobe...Just my opinion. I have respect for Kobe's talent, but there's just something about his personality, as it is portrayed in the media, that rubs me the wrong way. I actually kind of like LeBron, I won't lie.
