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.

Execution · Practiced Mastery
A licensed action shooter testing basic aim through cinematic scripted missions.

Execution · Practiced Mastery
Linear postwar crime story driven by cover shootouts and atmosphere.
James Bond 007: From Russia with Love leans Execution (Practiced Mastery); Mafia II leans Execution (Practiced Mastery).
James Bond 007: From Russia with Love leans a little harder on execution, though the gap is small.
James Bond 007: From Russia with Love
Lock-on shooting and driving need only basic dexterity
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.
James Bond 007: From Russia with Love
Henchmen follow scripted attack patterns
Mafia II
Enemies are scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
James Bond 007: From Russia with Love
Linear missions hide little
Mafia II
Story missions are fixed
Mafia II leans a little harder on optimization, though the gap is small.
James Bond 007: From Russia with Love
Gadget upgrades add a thin progression layer
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.
