What I call into question however is the notion that Jokic elevates his team more than Embiid. As such I'll direct our attention to career Net Rtg and On/Off to paint the picture as simply as I can. (If you aren't familiar with my opinions on this topic, I believe most "advanced stats" overemphasize box production to which they arbitrarily assign value. I don't consider umbrella metrics like that to be worthwhile because they don't translate to tangible meaning. As opposed to traditional box stats, new tracking data, or iterations of +/- where we know exactly how to interpret the information).
As promised, here is a season-by-season comparison for Net Rtg and On/Off respectively (bolded values indicate the "winner" in each stat category):
Embiid +3.0 / +11.1 ----- Jokic +2.3 / +9.5
Embiid +11.4 / +12.7 ----- Jokic +5.6 / +11.5
Embiid +7.7 / +10.5 ----- Jokic +5.2 / +10.2
Embiid +5.2 / +5.0 ----- Jokic +4.9 / +3.2
Embiid +12.4 / +12.3 ----- Jokic +4.4 / +6.2
Jokic put up +6.6 / +6.4 last year but there is no comparison for Embiid who is one season behind. Otherwise, it's a clean sweep for JoJo.
If your next thought was "OK but Jokic is more successful in the playoffs" I would beg to differ once again. Embiid's cumulative playoff Net Rtg is +9.5 and On/Off is +16.2. Jokic's cumulative playoff Net Rtg is -0.9 and On/Off is +5.2. Embiid leads both by a double digit margin.
When it comes to durability, I totally get that argument and wouldn't blame anyone for favoring Jokic on that basis. However, when the players actually play, I don't see any reason to believe the Joker is more impactful. That's not a knock on Jokic as Joel's on-court impact is truly astounding if you dive into the numbers. Hell, he put up a +3.0 Net Rtg as a rookie with the league's worst supporting cast featuring Nik Stauskas (led the team in minutes), Sergio Garcia and Gerald Henderson. Neither his offensive gravity nor defensive impact are captured in the box score, and that's what most fail to recognize when making this comparison.
If you disagree with the premise that Embiid is equally/more impactful than Jokic while on the court, please enlighten me with your thought process. I promise I'm a very open minded person

Adding RAPM below to rebut 'strength of teammate' arguments:
