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.

Optimization · Practiced Mastery
Slingshot trajectory puzzles with randomised bird hands gating consistency.

Execution · Practiced Mastery
The original top-down crime sandbox where you rack up points causing mayhem across three cities.
Angry Birds 2 leans Optimization (Practiced Mastery); Grand Theft Auto leans Execution (Practiced Mastery).
Grand Theft Auto leans a little harder on execution, though the gap is small.
Angry Birds 2
Trajectory precision on the slingshot matters modestly
Grand Theft Auto
Twitchy top-down driving and shooting under police pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Angry Birds 2
Pigs sit in structures, never adapting
Grand Theft Auto
Cops follow simple scripts; nothing adapts
Angry Birds 2 leans a little harder on variance, though the gap is small.
Angry Birds 2
Random bird-card hands and multi-stage levels shuffle each attempt
Grand Theft Auto
Chaotic traffic and wanted-level escalation surprise players
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Angry Birds 2
Knowing structure weak points and bird matchups is the edge
Grand Theft Auto
Score targets reward learning missions and city layouts
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.
