My rankings are something like this
Top 3 - Wilt, Lebron, Jordan
Next 4 - Kareem, Magic, Larry, Bill
Next 5 - Duncan, Hakeem, Shaq, Oscar, Moses
Next 5 - West, Durant, Garnett, Dr. J, Mailman
Kobe is probably next, but I'd listen to arguments on Robinson, Baylor, Barkley, Dirk, and Curry. So somewhere in the 18 to 23 range all time right now and if Curry gets healthy and regains his form, I think he passes him up rather easily when all is said and done (not to mention someone like Giannis coming down the pipeline).
Kobe had just 1 league MVP (and it isn't like Lebron wasn't the best player that season - Lebron scored more, rebounded more, assisted more, etc., it was just the writers weren't quite ready to crown the king). There are legitimate arguments that he was never even the best player on a title team (he probably was in 09, but I do think Pau was better in 10). As great players go, especially ones known for scoring, Kobe was pretty darn inefficient (his career best TS% was 58% and his average was 55%). That compares very poorly with the other truly great players. Lebron for comparison has a career TS% average of 58.6% (so better than Kobe's best season). Harden, who seems to have that Kobe in him (offensively), has a career TS% of 61%. Heck, if Harden ever breaks through and wins a title, even with his atrocious defense, I think he could pass Kobe on the all time lists given just how efficient a scorer he is (and every bit as prolific). Harden clearly has perception problems, but his last few seasons have been truly impressive when you actually look at them. He just suffers from the same affliction as the Mailman, Barkley, etc.
