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
Mowing scripted alien hordes while optimising stats and weapon spending.

Execution · Practiced Mastery
The saga's flashy conclusion sending Sora through Pixar and Disney worlds toward the Keyblade War.
Alien Shooter 2 Conscription leans Execution (Practiced Mastery); Kingdom Hearts III 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.
Alien Shooter 2 Conscription
Kiting and shooting dense hordes rewards clean control
Kingdom Hearts III
Limit Cut bosses require sharp reactions
Kingdom Hearts III leans a little harder on reads, though the gap is small.
Alien Shooter 2 Conscription
Monsters charge in scripted waves
Kingdom Hearts III
All opposition is scripted spectacle
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Alien Shooter 2 Conscription
Spawns are fixed per mission once seen
Kingdom Hearts III
Minimal hidden systems
Kingdom Hearts III leans a little harder on optimization, though the gap is small.
Alien Shooter 2 Conscription
Stat builds and weapon economy decide horde survivability
Kingdom Hearts III
Attraction commands or boss study both solvable
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.
