ignition map best if you have a knock sensor.... to here if there is any knocking.... from there u can tune ur ignition.. who suggest you go to a place where their dyno can apply loading.. both maps can be tune to your liking
power FC can read knock.. but that is using your original knock sensor.. which sometimes reacts to certain vibration in ur engine bay that isn't pinging.. seriously its better than you tune on the dyno..
