Respect? I guess this is asking who I regard higher or admire more as an athlete.
While I have seen a player (Jordan) do what Kobe does and do it just a bit better, I have never seen quite the same basketball player as Lebron before. In that sense I have slightly higher regard for Lebron's skills. But we are talking about 2 of the greatest ever and respect for their skills should be pretty close to equal.
If analysis involves work traits like work ethic, team camaraderie, competitiveness, I'd say Kobe wins on competitiveness, Lebron wins on camaraderie, and they are probably equal with regard to work ethic.
As far as personal likability goes, I despise Kobe and dislike Lebron.
