head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is optimization, and it is a single point.

Execution · Practiced Mastery
Learning scripted mission layouts and executing aim and stealth under pressure.

Execution · Practiced Mastery
Brutal cinematic stealth-action sequel where execution under pressure decides fights.
Syphon Filter 3 leans Execution (Practiced Mastery); The Last of Us Part II leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Syphon Filter 3
Aim, taser timing and stealth movement carry encounters
The Last of Us Part II
Faster, more demanding combat and dodge timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Syphon Filter 3
Enemies run fixed scripts, never model the player
The Last of Us Part II
Smarter AI still runs mappable search scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Syphon Filter 3
Enemy placements are scripted-but-unknown on first runs
The Last of Us Part II
First-encounter unknowns only
Syphon Filter 3 leans a little harder on optimization, though the gap is small.
Syphon Filter 3
Routes, gadget use and mission layouts are fully learnable
The Last of Us Part II
Crafting economy and encounter route planning
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.
