LeBron is legitimately in the conversation for GOAT, which is a massive statement in itself.
One point I'm always surprised people never bring up is that while Jordan never hopped around to different teams, he also never really achieved anything without Pippen and Phil Jackson. People hold it against LeBron because he moved around, as though it's easy to join a new system and create a contender in the blink of an eye. Jordan just had to rinse and repeat what he did every year once the pieces were in place. Sure, he added the most lethal fade-away post move of all time as he got older, but he never really had to deal with team change the way LeBron did. He didn't have to figure out how to make it work by himself, then make it work with Wade/Bosh, then make it work with Kyrie and Love, then make it work basically by himself again.
I really admire LeBron's ability to excel with such a wide range of Alphas (and no Alphas) around him. If Jordan had taken the same career path LeBron did, I don't think he would've found LeBron's success. I think he would have had some years where his competitive nature would've just alienated the other Alpha(s), kind of like prime Kobe did with Shaq, and shit would've imploded.
Kind of tied to that, it really seems like LeBron will be remembered as a guy who controlled his own destiny. He moved where he wanted to when he wanted to, and success followed him. He didn't put his fate in the hands of a franchise--he did his thing when he wanted to. Jordan spent years complaining about "Crumbs", but he never really took charge beyond the court, except to quit and then un-quit. Given his career as a Wizard and then a GM, it was probably good that he didn't.
You could say Jordan was just being loyal to a franchise, which is true, but the essence of loyalty is to cede control of part of your fate to someone else. Personally, I often value autonomy over loyalty, so maybe that's why I admire LeBron's achievements more.
I'm glad I got to watch both in their primes. LeBron has my vote for GOAT, but I can definitely see how reasonable people could disagree.
