In my opinion, this is EASILY the best album Bruce ever did.
License to Ill is incredible for the genre, in fact, it's sometimes noted as being genre-defining. One of the best albums from the "golden age of hip hop" with a lot of good tunes on it.
Like both albums, but I'm giving my vote to the Beasties for originality, innovation and downright pleasurable sampling of some great classic rock tunes as well as old school funk.
