to me, there's a different between who's the most-skilled and who is my favorite...i'd probably say that jacka is my fav mob figa, but based on pure lyrical skill/talent:
Rydah & AP-9 tied for first
Fed-X
Jacka
Huss
as far as who i like to bump in the ride i'd go jacka, rydah, ap-9, then fed-x and huss
