I think if you're trying to maximize the peak-production out of your team with strong supporting casts, Kawhi will be a better option (this is Kawhi at his best).
That is probably true, but only when it comes to median competition and regular season mostly. Players like Lebron (Wilt, Shaq etc), are a guarrantee that you will have a succesful regular season and be the favorite against most teams, more so than the players like Kawhi. They are too much for the ordinary opponent to handle.
But when it comes to playing against good teams, with good talent and a competent coaching stuff in the knockout stage, Kawhi is more valuable. The physically dominant players leave little room for adjustment and optimum team play. With Lebron, you would just let him shoot and clog the paint when his supporting cast is weaker or let him drive endlessly and shut down the shooters when the supporting cast is elite, and both strategies will be certifiably succesful. On the other hand there is no obvious way you could capitalize on Kawhis' basketball attributes to gain the advantage.
