Iron Man is a great album but more of a group album of Ghost, Rae and Cap. Also when it dropped I think it was looked at inferior to OB4CL as well as Liquid Swords at the time and didn't get the praise it deserved.

SC meanwhile came out after a lot of mediocre Wu albums, Tical 2000, Bobby Digital, Uncontrolled Substance. You can disagree with mediocre but they weren't the classics we were used to but then Ghost came thru with another classic with SC and back on top again.

Ghost kept it going with a string of pretty damn good albums but nothing quite as good as SC was. Rae had a little resurgence and there has been some pretty good albums since but really the last straight up classic the Wu had was Suprme Clientele to me.
