1) Devil's Night
2) 8 Mile soundtrack
3) Hell: The Sequel
4) The Re-Up
5) Slim Shady EP
6) Refill
7) D12 World
8) Curtain Call
I wouldn't consider putting Refill in this list only because it is barely half an album and can't compete to full length albums.
I think that Devil's Night is even, if not better than Recovery, for a group album that is. Aswell as being on par with Relapse, quality wise.
Re-Up only for No Apologies, Public Enemy #1 and You Don't Know. No Apologies is a very under rated song.
Hell: The Sequel is not a full length album but the awesome-ness of it makes up for that.
Curtain Call is last because I don't think it should be in this list only because it is a greatest hits album with a few new tracks.
D12 World is meh, few good songs.. (How Come and Get My Gun come to mind). This and Curtain Call compete for last place.
8 Mile is second for obvious reasons (Lose Yourself, 8 Mile, Rabbit Run....etc)
Slim Shady EP is better than some but not good enough for the top spots.
