big l >>>>>>>> both of them
He's been surpassed,his punchlines is better and he's been doin em way longer and more consistently than big l did at a high level....how can u argue that when Fab playin with triple and quadruple entendres....multi wise since we must go there id say they Fabs proven he's equally skilled there, and with Fab showing more flow advancement over the years he gets the nod clearly now....Mase is questionable since he bowed out prematurly....as Murda Mase I thought he wuz a better listen than L or Fab but its not enuff of that material.

Not a wasted word,or wasted line trying to come up with a cute punchline that won't age well,just raw shyt.

! Big L was way ahead of his time....he's a whole different animal than Mase or Fab 

Ok, you must've just started listening to rap music...
