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.

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

Optimization · Systems & Chaos
A gentle hidden-object hunt through painted insect scenes with light puzzles.
L.A. Noire leans Optimization (Systems & Chaos); Morphopolis leans Optimization (Systems & Chaos).
L.A. Noire leans a little harder on execution, though the gap is small.
L.A. Noire
Light shooting and driving, very forgiving
Morphopolis
Clicking painted scenes needs no dexterity
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
Morphopolis
No opponent of any kind
L.A. Noire leans a little harder on variance, though the gap is small.
L.A. Noire
Interrogation tells and clues hidden until discovered
Morphopolis
Hidden objects are scripted-but-unknown until spotted
L.A. Noire leans a little harder on optimization, though the gap is small.
L.A. Noire
Evidence chains and question choices have fixed correct answers
Morphopolis
Simple puzzle chains have single fixed answers
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.
