head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

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

Execution · Practiced Mastery
An action-leaning stealth entry where aggressive optimal clears replace pure ghosting.
Syphon Filter 3 leans Execution (Practiced Mastery); Tom Clancy's Splinter Cell: Conviction 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
Tom Clancy's Splinter Cell: Conviction
Mark-and-execute flow rewards quick, accurate play
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
Tom Clancy's Splinter Cell: Conviction
Enemies search via scripted last-known-position logic
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
Tom Clancy's Splinter Cell: Conviction
Mild uncertainty in enemy search behavior
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Syphon Filter 3
Routes, gadget use and mission layouts are fully learnable
Tom Clancy's Splinter Cell: Conviction
Encounter rooms have clear optimal clear orders
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.
