Difference between mod_dosevasive and APF?

Hi:
I was wondering, what's the main difference between mod_dosevasive and APF? Don't both basically block suspicious IPs using IPtables? Not sure which one to install, perferably the one with 0 post maintanance, since I'm not good with server admin and checking if legitimate IPs are blocked etc.

Thanks,
