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

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

Execution · Practiced Mastery
Linear postwar crime story driven by cover shootouts and atmosphere.
L.A. Noire leans Optimization (Systems & Chaos); Mafia II leans Execution (Practiced Mastery).
Mafia II leans clearly harder on execution.
L.A. Noire
Light shooting and driving, very forgiving
Mafia II
Cover shooting and fistfight timing
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
Mafia II
Enemies are scripted
L.A. Noire leans clearly harder on variance.
L.A. Noire
Interrogation tells and clues hidden until discovered
Mafia II
Story missions are fixed
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
Mafia II
Modest; learning encounter layouts
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.
