head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Pure Mechanics
Treyarch's future-tech Call of Duty that anchored competitive console FPS.

Execution · Practiced Mastery
The long-running American football simulation series.
Call of Duty: Black Ops II leans Execution (Pure Mechanics); Madden NFL Football leans Execution (Practiced Mastery).
Call of Duty: Black Ops II leans a little harder on execution, though the gap is small.
Call of Duty: Black Ops II
Snap aim and movement speed decide split-second gunfights
Madden NFL Football
passing, running, and tackling precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty: Black Ops II
Human lobbies adapt rotations; pros mind-game spawns
Madden NFL Football
human opponents disguise and read plays
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty: Black Ops II
Spawn flips and scorestreak chaos inject randomness
Madden NFL Football
fumble and injury randomness
Madden NFL Football leans a little harder on optimization, though the gap is small.
Call of Duty: Black Ops II
Pick-10 classes and streak economies reward optimization
Madden NFL Football
playbook and roster management depth
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.
