He doesnt need to use a voice synthesizer (sp?) to make his songs better, he doesnt need to make constipated noises or dying animal noises in his songs either and Carter sounds like that.
Dont get me wrong i love lil wayne, but Eminem is by far the best rapper in every area hands down. Eminem kills everyone in freestyle, he raps about things to him that mean something, he has sick beats and he's just the lyrically.
Lil Wayne .Em went crap after rapping about the same things and him and Proof were the Only good ones in D12 after Proof died Em's career just faded away but he does have his good singles here and there
