Eminem's is better/more hilarious, obviously.
I was obsessed with Eminem from age 11 to about age 13 and I agree with atsonicpark - his first two albums are amazing. I haven't heard any full albums past The Eminem Show but when comparing the "hit" songs from Encore vs. those of Relapse, the latter definitely comes out on top.
Also lol @ Nick Cannon being the host of America's Got Talent.
