Forti is preferred for raw stats (dmg, some rest, def). Some people fail to consider what they need their Merc to accomplish. Few end game builds rely on Merc killing (good example is a nec needs Merc with high CB and attack speed to be a viable boss killer). Most mercs just need to stay alive, which means coh can with well to add res+life leachband still have a lot of damage vs most monster types.
I use coh on Merc when he needs fire absorb like in Chaos and helm is steel shade. I also use on Java Merc with same setup for hydras on baal waves.
