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 · Practiced Mastery
A co-op third-person shooter built around two mercenaries juggling enemy aggro together.

Optimization · Practiced Mastery
Grim stealth horror about luring scripted hunters into executions.
Army of Two leans Execution (Practiced Mastery); Manhunt leans Optimization (Practiced Mastery).
Army of Two leans a little harder on execution, though the gap is small.
Army of Two
Cover shooting and co-op timing
Manhunt
Stealth timing on executions
Army of Two leans a little harder on reads, though the gap is small.
Army of Two
Aggro system is mappable, not adaptive
Manhunt
Hunters patrol on scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Army of Two
Scripted setpieces
Manhunt
Patrol noise reactions add small unpredictability
Manhunt leans a little harder on optimization, though the gap is small.
Army of Two
Weapon upgrades and aggro manipulation
Manhunt
Shadow routes and lure tactics are learnable
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.
