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.

Optimization · Pure Optimization
Deeper sequel turning occupied-Europe missions into intricate solvable stealth puzzles.

Optimization · Pure Optimization
The original stealth assassination sim where each mission is a clockwork puzzle.
Commandos 2: Men of Courage leans Optimization (Pure Optimization); Hitman: Codename 47 leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Commandos 2: Men of Courage
Multi-commando coordination under timing windows
Hitman: Codename 47
Stiff aiming and unforgiving stealth movement
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Commandos 2: Men of Courage
Scripted patrols with no adaptation
Hitman: Codename 47
Guards follow fixed scripted patrols
Hitman: Codename 47 leans a little harder on variance, though the gap is small.
Commandos 2: Men of Courage
Vision cones shown; layouts fixed
Hitman: Codename 47
First-run guard routes and triggers are unknown
Commandos 2: Men of Courage leans a little harder on optimization, though the gap is small.
Commandos 2: Men of Courage
Open-ended missions still reduce to solved routes
Hitman: Codename 47
Learning the level clockwork is the whole game
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.
