Hmmm I admire both of'em. Most people would automatically say Biggie, since he's no longer here and one of tha most influential MCs in Hip-Hop. So i honestly don't know, they're both real lyrical. Biggie was all about lyricism and making you feel him with his punchlines and Nas is/was all 'bout lyricism aswell, but making you think at tha same time [especially old Nas] like songs like "Heaven". Both real vivid with storytelling... I'm leanin' towards Nas though.... iunno lol this is a good one.
