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

Execution · Practiced Mastery
A grittier crime story where weighty driving and gunplay carry the experience.

Execution · Practiced Mastery
Lara's reboot blending cover shooting, climbing, and survival cinema.
Grand Theft Auto IV leans Execution (Practiced Mastery); Tomb Raider (2013) 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.
Grand Theft Auto IV
Heavier driving and cover shooting reward control.
Tomb Raider (2013)
Bow aim, QTEs, and platforming timing matter.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto IV
Scripted AI, no adaptive opponent modeling.
Tomb Raider (2013)
Scripted enemy waves, no adaptation.
Grand Theft Auto IV leans a little harder on variance, though the gap is small.
Grand Theft Auto IV
Minor mission variance.
Tomb Raider (2013)
Minimal randomness in encounters.
Tomb Raider (2013) leans a little harder on optimization, though the gap is small.
Grand Theft Auto IV
Mission routing and weapon picks learnable.
Tomb Raider (2013)
Weapon upgrades and skill picks straightforward.
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.
