head to head
For Honor asks more than Chivalry: Medieval Warfare, and the gap is reads.

Execution · Competitive PvP
First-person medieval melee where feints and drags duel human reads.

Reads · Competitive PvP
Directional melee fighter with deep mixups.
Chivalry: Medieval Warfare leans Execution (Competitive PvP); For Honor leans Reads (Competitive PvP).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Chivalry: Medieval Warfare
Swing manipulation, footwork, and parry timing
For Honor
Direction-based attacks need fast inputs
For Honor leans clearly harder on reads.
Chivalry: Medieval Warfare
Feints and drags against adapting humans
For Honor
Mixups versus parries are pure reads
For Honor leans a little harder on variance, though the gap is small.
Chivalry: Medieval Warfare
Battlefield chaos with many players
For Honor
Revenge build and ganks add swings
For Honor leans a little harder on optimization, though the gap is small.
Chivalry: Medieval Warfare
Class loadouts and objective knowledge
For Honor
Hero kits and feat builds tuned
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
