Rap & Hip Hop: Mos Def and Talib Kweli are Black Star or Black on Both Sides?

Two of the most encompassing and prolific conscious rap albums in history - which do you think is better?

Personally I would go with Black on Both Sides. It just covers so much more ground, it's almost the project of a visionary, both musically and topically. Black Star has a really nice stripped down production, which benefits Talib, but gives the album an almost dialectic feel. Black on Both Sides ranges from lush, beautiful, atmospheric beats to that same grimey feeling, giving Mos a range from the almost spiritual to introspective, to a father by a fireside.

BQ: B/S, People's Instinctive Travels and the Paths of Rhythm is on par with The Low End Theory?

BQ2: Rank Travels, Low End Theory, and Midnight Marauders.
