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.

Execution · Pure Mechanics
A space dogfighter testing drift maneuvers and tracking aim against scripted squadrons.

Execution · Pure Mechanics
Push-forward arena FPS where movement and aim are the whole game.
Chorus leans Execution (Pure Mechanics); DOOM (2016) leans Execution (Pure Mechanics).
DOOM (2016) leans a little harder on execution, though the gap is small.
Chorus
Drift turns and dogfight aim are the whole combat test
DOOM (2016)
Aim, movement, glory-kill timing all peak.
DOOM (2016) leans a little harder on reads, though the gap is small.
Chorus
Enemy pilots fly scripted AI routines
DOOM (2016)
Demons scripted attack patterns.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Chorus
Little hidden beyond unexplored map corners
DOOM (2016)
Minimal encounter randomness.
DOOM (2016) leans a little harder on optimization, though the gap is small.
Chorus
Weapon swapping and upgrade picks add a light layer
DOOM (2016)
Rune and weapon mod picks meaningful.
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.
