Classic Fisk wins.
Back in the day, not only was he giving Spidey problems strength wise, but he was fast to boot. For his stature, KP ALWAYS caught his opponents off guard. Skill wise, the man has trained with over a 1/2 a dozen black belts and red belts, some of which were armed, and still defeated them in less than 20 seconds.
Kingpin(non classic) also fought Bats and stalemated him. Classic KP would beat Bane pretty handily imo.
