And I am really into setbacks. I think it's as good as his latest release. OD is really good too but Kendrick was still finding his sound on that I would put it over everything else but Section 80 and GKMC are still definitely better for me.
OD was a really good album but Section 80 blew my mind when It came out. His song making skills expanded greatly on that one and on GKMC he expanded his album making skills. GKMC is basically boys in the hood 2 they should make a movie out of if, it could be better than 8 mile.
I think you may have a case of "he used to be all mine" disease where you stop liking an artist as much when everyone else discovers him.
