At their absolute respective peaks, Jokic is on the same level as them. All 3 are/were uniquely monstrous in their own way. Jokic has actually sustained his other wordly performance (production, efficiency, etc) for more consecutive seasons than Steph or KD ever did. Granted, so has Giannis and Embiid from a regular season perspective.
Difference with Jokic compared to all the others mentioned, is that his title run last year under the brightest lights is p4p one of the best/most impressive ever when factoring strength of schedule and how he packed up Gobert/Towns/KD/Ayton/Book/LeBron/AD/Butler/Bam.
Didn't crash and burn in the playoffs, nor did he ever look shaky or need to benefit from key injuries to the ops to survive a series enroute to his title. It was just pure domination from October through June.
