Styles P. Hands down.
If you want consistent guest verses, ill punchlines, a voice that'll make you frown your face up, and some swag on top of it all, you go with Jada.
If you want a quasi-introspective, meaningful but gritty, equally sick flow and delivery, while riding out to catch a body in any number of ways, or you just on some shyt, and in a mood, then you go wit the Ghost.
I vote S.P. tho.
