Yeah
Big Pun most definitely
But on some of his last recordings he sounds like he's too fat to breathe let alone flow
also Krayzie Bone
and on a Good Day :
Daz Dillinger!!! (the Dogg Food Album, " In California","Represent that G.C." and most recently "Round & Round")
And Crooked I seems to have the craziest Flows in LA ("Step up" "Gangsta Rap")
And I cant forget TREACH from the old Naughty Albums he was the Illest in the early Nineties (IMO)
