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 · Practiced Mastery
A snowboarding sim testing trick execution and line selection for high scores.
Ace Combat 7: Skies Unknown leans Execution (Practiced Mastery); Mark McMorris Infinite Air 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.
Ace Combat 7: Skies Unknown
Tight dogfighting and missile-dodge timing
Mark McMorris Infinite Air
Trick timing, rotation and landing control define runs
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
Mark McMorris Infinite Air
Solo and scored runs, no adaptive opponent
Mark McMorris Infinite Air leans a little harder on variance, though the gap is small.
Ace Combat 7: Skies Unknown
Cloud cover gimmicks are learnable
Mark McMorris Infinite Air
Procedural terrain adds some unpredictability
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Ace Combat 7: Skies Unknown
Aircraft tree and loadout routing matter
Mark McMorris Infinite Air
Trick chaining and line selection optimize scores
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.
