I love both groups, but I gotta give the edge to outkast
Had a longer run with 5 classic albums as a group
Plus, they never really fell off
Idlewild may be their weakest album compared to the rest of their discography, but it's still got a lot of great music on it
Wu has classic solos of course, but seemed to have lacked a vision for what the group should do after wu tang forever
Whereas outkast just kept reaching higher and higher highs
Big boi and andre grew not only as rappers, but as producers as well
They pretty much accomplished everything they could do
Which is why I feel they haven't came back. Really nowhere else to go but down
