i think encore and sslp are about the same. encore is better than he gets credit for on it, although there were some definite throwaways on there, i just didnt think the production was that good on sslp. mmlp and eminem show are his best hands down with recovery right behind. relapse is his worst effort and its still better than most shit that dropped last year.
but i agree with 20sixx. eminem is hella overrated. i can name rappers on milk cartons better than this dude. no punchlines, no wordplay, no delivery, nothing. dude is straight trash. people only think he's a good rapper because he's white.
