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

Optimization · Pure Optimization
A western stealth-tactics game solved by planning perfect takedown chains.

Optimization · Pure Optimization
The original stealth assassination sim where each mission is a clockwork puzzle.
Desperados: Wanted Dead or Alive 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.
Desperados: Wanted Dead or Alive
Quick-action setups demand precise simultaneous timing
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.
Desperados: Wanted Dead or Alive
Enemy view cones and patrols are fully scripted
Hitman: Codename 47
Guards follow fixed scripted patrols
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Desperados: Wanted Dead or Alive
Layouts hidden only on first pass, then known
Hitman: Codename 47
First-run guard routes and triggers are unknown
Desperados: Wanted Dead or Alive leans a little harder on optimization, though the gap is small.
Desperados: Wanted Dead or Alive
Optimal takedown sequencing solves each western vignette
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.
