I'm going with Lajoie on this one:

His MC Vagina shit blows any punchlines and metaphorz Eminem comes up with out of the water.
"I'm Che Vagina, I liberate girls from oppressive pants"...
"By that I mean I've had sex with a girl on her period, that's right/I don't mind ketchup on my hotdog, as long as the bun is tight"
Listening to Lajoie do his thing, you can see why Eminem is not the GOAT. In order to be the GOAT, you must be good at the metaphorz, and Eminem is an epic fail in this area. All Eminem was ever good at is multis.
Therefore, there are MANY rappers better than him, they just don't get the attention and hype.
