Can't really rate Infinite, so otherwise:
SSLP-4/5(Eminem trying his best, hungriest)
MMLP-4.5/5(Eminem at his angriest, most creative)
TES-5/5(Eminem at his prime, riding the wave to produce a perfect album)
Encore-2/5(Reminiscent of TES but in very few ways, you can tell he was self destructing)
Relapse-3/5(Decent yet unfocused return, crazy rhyming)
Recovery-3.5/5(Great return to form, not his best, but up there)
