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

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

Execution · Pure Mechanics
Classic WWII shooter whose objective-based multiplayer defined a genre.
Call of Duty: Black Ops II leans Execution (Pure Mechanics); Return to Castle Wolfenstein leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty: Black Ops II
Snap aim and movement speed decide split-second gunfights
Return to Castle Wolfenstein
Fast strafing and precise hitscan aim dominate duels
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
Return to Castle Wolfenstein
Multiplayer objective pushes hinge on outguessing human defense
Call of Duty: Black Ops II leans a little harder on variance, though the gap is small.
Call of Duty: Black Ops II
Spawn flips and scorestreak chaos inject randomness
Return to Castle Wolfenstein
Fixed objectives and scripted singleplayer enemies, little randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty: Black Ops II
Pick-10 classes and streak economies reward optimization
Return to Castle Wolfenstein
Objective timings, class roles, and routes reward planning
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.
