RZA presents a good challenge, if we go artist for artist, album for album, you might say he's better.

Meth, Ghost, Rae, Dirty, GZA

Snoop, Em, Kendrick

Dre's artist certainly have had a greater impact. I'm not sure if Dre gets credit for Eazy, they both kind of came up together.

Jay brought Kanye, Beans, Free...RiRi?

Ye hasn't done much outside of signing established artists.

There's not a whole lot of comp for Dre, but I'd say RZA comes damn close.
