I really don't see what's so bad about thinking LeBron with 3 rings, 3 Finals MVP and one or two MVP's can be argued to have a superior career than Kobe. At that point all Kobe would really have over him is longevity and two more rings.
I would also take peak LeBron over peak Kobe. Just my opinion. I'm not about to get into a Kobe/LeBron argument.
But here's a better way to end the argument. RUSSELL > Both.
I wouldn't say superior career IF Lebron does that might have be 4 rings but better overall sure. I truly believe peak Kobe was just better player than peak Lebron was. It really comes down to what do you prefer. If I am starting team with great talent around me with any of these positions such as dominate center, SF, PF, and PG I'll take Kobe. Likewise, if have little to no talent with a team filled with below average players I'll take Lebron.
Kobe better in these areas:
Skilled superior basketball skills like MJ, Bird, and Magic were.
Higher basketball IQ
Handles (ball handling)
On the ball defender.
Post up game, midrange, and 3 point shooting.
Free throw shooting
Lebron better in these areas:
More versatile on D and O. Can play more positions on Defense and Offense.
Unstoppable driving to the lane.
Makes his teammates around him player better.
This is my view on it.
