HELL NO! JayZ is definitely the Michael Jackson of the rap game. They're both overrated like crazy. MJ's voice wasn't GOAT level, the same way Jay's rap skills aren't GOAT level.... but ask the average fan and these guys are the best hands down. They're the ones in the spotlight, so they're the ones that get credit for everything.
Nas is ACTUALLY the all-around best as far as body of work, longevity etc. So he would be someone like Stevie Wonder. Real niggas know he's the best, but real niggas are at an all-time low. Most people will ride with the pop star because he's in their face all the time.
