what is better eminem era rappers or lil wayne era rappers

They both suck though Eminem sucks far less than Lil Wayne. Lil Wayne is, quite simply, hateful and wasted.

eminem owns the show always has and always will, the answer to your question is old skool rappers are alot better than these new ones, there are a couple of good ones floating around, game is sick, yelawolf potentially, true rap seems to be a dying breed.
