Who else agrees with mos def, DOOM is incredible?

mf doom is probably one of the great lyricist of our time. he just incredible. Madvillainy is, in my opinion, the greatest hip hop album of all time. Lupe fiasco has some great wordplay also (see:dumb it down, The coolest) What you guys think? You guys agree or disagree? tell me why and most convincing gets the best answer. also tell me your favorite lines from DOOM or any other rapper!
