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 · Pure Mechanics
Landmark FPS built on physics puzzles and tight gunplay.

Execution · Practiced Mastery
Stylish aim and slow-motion positioning against waves of scripted goons.
Half-Life 2 leans Execution (Pure Mechanics); Stranglehold 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.
Half-Life 2
Gravity gun and shooting demand precision.
Stranglehold
Slow-motion dive-shooting still rewards aim and style timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life 2
Combine AI scripted, non-adaptive.
Stranglehold
Goons spawn in scripted waves, never adapting
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life 2
Almost no randomness.
Stranglehold
Destructible arenas play out the same each run
Stranglehold leans a little harder on optimization, though the gap is small.
Half-Life 2
Linear progression with no builds.
Stranglehold
Style-point economy and Tequila Time management are learnable
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.
