Albums:
So how do their best albums stack up against each other? There’s no public consensus one way or the other, so this is completely a judgment call. That said, we’re pitting The Black Album vs. Marshall Mathers, and we’re giving the edge to Jay.

Also worth nothing: Both have seen their skills decline as they’ve aged but, remarkably, this has had not much impact on their commercial relevancy: Eminem’s Recovery has had even more success than Relapse, and Jay’s “Empire State of Mind” — off the uneven Blueprint 3 — is the biggest single of his career.
Edge: For not front-loading his best albums early on, Jay takes it.
