i could see famine's powers as being more of a paralyzer. he saps the energy from their bodies therefore slowing their movements making it easier for the quick kill or eventually they just kind of shut down from lack of energy.
pestilence would of course be the annoying guy who constantly decreases your health by poisons
 
the counterparts 
fury would more than likely be a chaos maniac who aquires chaos at twice the rate of the rest of the horsemen
strife would however be extremely fast like the archer on gauntlet legends
