Explain the Jokic vs Giannis debate

I always see from Jokic fans from the past 2-3 seasons that Jokic is better than Giannis. But right now, they describe Jokic as the "clear cut MVP" compared to Giannis.

I'm a casual fan so please treat me as such. But for people out there that regularly watch Jokic and Giannis play. Could you please tell me what Jokic is doing this season that makes him the clear cut MVP compared to Giannis or the other superstars. Because if people are going to bring up stats, Giannis is not that far behind if we even call it being behind. Only player in this era that is averaging 30+ppg 12+ppg 6+apg on 60% fg shooting.
