Com definitely had one of the best runs from Resurrection to LWFC.
Not sure I would say he was the best 'spitter' that entire time but when taking everything into account, he probably was the most consistent and is right there with Kast as having the best 4 albums in that time frame.
EC did hurt him a bit in my opinion. I know some people loved it but it was the moment where I felt that he became a follower. It was like he went in trying to make his Stankonia and it just didn't come off natural to me.
He came back pretty strong with Be but in retrospect, I think that album benefited a lot from coming after EC and from Kanyes success. Not a bad album by any means and I can still rock with it, but I don't think it's as good as his Resurrection-LWFC run at all.
Be, Finding Forever, and The Dreamer/The Believer are a slow decline but still a decent end of career run. UMC was just an embarrassment.
