head to head
Neither is simply harder - they are hard in different places. L.A. Noire demands more execution; Unheard demands more optimization.

Optimization · Systems & Chaos
1940s detective procedural built around crime scenes and reading scripted interrogation tells.

Optimization · Systems & Chaos
An audio detective game where you identify suspects by eavesdropping on crime-scene recordings.
L.A. Noire leans Optimization (Systems & Chaos); Unheard leans Optimization (Systems & Chaos).
L.A. Noire leans clearly harder on execution.
L.A. Noire
Light shooting and driving, very forgiving
Unheard
Just scrubbing a timeline and listening
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
L.A. Noire
Suspects follow fixed scripts, never adapt
Unheard
No opponent, recorded voices only
Unheard leans a little harder on variance, though the gap is small.
L.A. Noire
Interrogation tells and clues hidden until discovered
Unheard
Identities are hidden until audio clues connect
Unheard leans clearly harder on optimization.
L.A. Noire
Evidence chains and question choices have fixed correct answers
Unheard
Cross-referencing fixed conversations solves each case
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.
