I guess it depends on what type of freestyle ure talking about? I mean, battle rap....conceptual...just step in the booth rip off a freestyle recorded!? Conceptually, itd be hard to not mention Supernatural for the fact that he is in the Guinness......Big L would have to be my favourite because his freestyles were on his albums and sounded so raw...Those 2 stand out 4 me too.....id say Papoose has some goodies too.....but in all honesty, theres gotta be many freestyle rappers who are unknown, so those are my 3 nominations
