#8 is the nostalgia pick. Frobe was a showman like none before and low cut Kobe from '05-'06 was historic. #24 from '07 - '13 was a better player and leader in every metric outside of athleticism.
His footwork? Improved. Midrange? Impeccable. Skill level? Never better. Feel for the game? Considerably superior. Leadership? It's not even close.
#24 is only glossed over today because guys remember the final three to four years where he was a shell of himself. In real time when he was rattling off 4 straight 50 point games the season after switching numbers and leading the Lakers as the guy to 3 straight final appearances, no one was claiming he an inferior version. The sentiment was that he was better than he had ever been.
#24 was a better leader, more refined, and smarter.
