I also actually prefer Lebron over Kobe too.
Lebron has better basketball IQ, makes the players around him better, and has even carried a team single-handedly into the NBA Finals (2006-2007 Cavaliers). And who will forget his solo performance in the 2015 Finals without Kyrie and Kevin Love?
LBJ also has less off-court distractions than Kobe did in his career. Had Kobe worked better with Shaq and not gotten into all these other off-court shenanigans, the Lakers would have probably won more titles.
