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 squad shooter about leading a resistance through occupied New York, balancing gunplay with simple squad orders.

Optimization · Practiced Mastery
A stealth-action game where planning routes past scripted guards is the deep skill.
Freedom Fighters leans Execution (Practiced Mastery); Metal Gear Solid 2: Substance leans Optimization (Practiced Mastery).

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.
