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

Execution · Practiced Mastery
A modern arcade flight game of high-speed dogfights, drones, and dramatic canyon runs.

Execution · Pure Mechanics
Open-world racing testing car control and line discipline with light tuning underneath.
Ace Combat 7: Skies Unknown leans Execution (Practiced Mastery); Forza Horizon 2 leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Ace Combat 7: Skies Unknown
Tight dogfighting and missile-dodge timing
Forza Horizon 2
Racing lines, braking points and car control lead everything
Ace Combat 7: Skies Unknown leans a little harder on reads, though the gap is small.
Ace Combat 7: Skies Unknown
Campaign AI scripted; small PvP scene adds little
Forza Horizon 2
Drivatar AI mimics styles but stays effectively scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Ace Combat 7: Skies Unknown
Cloud cover gimmicks are learnable
Forza Horizon 2
Weather shifts grip slightly; courses are fully known
Ace Combat 7: Skies Unknown leans a little harder on optimization, though the gap is small.
Ace Combat 7: Skies Unknown
Aircraft tree and loadout routing matter
Forza Horizon 2
Car tuning and route knowledge reward preparation
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.
