What makes Jay z the best rapper of all time?

HOV has been considered the best rapper alive by so many rap fans and critics and I truly love his music. I've only listened to 3 albums from him (blueprint 1, blueprint 3, watch the throne, the black album) and I know that's not enough for me to form an option. That's why I'm listening to more. What I wanna know tho is what makes him the GOAT both in your eyes and the critics eyes
