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
Push-forward arena FPS where movement and aim are the whole game.

Execution · Pure Mechanics
Arcade driving that tests cornering execution over a small set of memorisable tracks.
DOOM (2016) leans Execution (Pure Mechanics); Need for Speed II leans Execution (Pure Mechanics).
DOOM (2016) leans a little harder on execution, though the gap is small.
DOOM (2016)
Aim, movement, glory-kill timing all peak.
Need for Speed II
Cornering and throttle control decide every race
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
DOOM (2016)
Demons scripted attack patterns.
Need for Speed II
AI racers follow rubber-banded scripts, not minds
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
DOOM (2016)
Minimal encounter randomness.
Need for Speed II
Tracks are fixed; nothing meaningful is hidden
DOOM (2016) leans a little harder on optimization, though the gap is small.
DOOM (2016)
Rune and weapon mod picks meaningful.
Need for Speed II
Learning six tracks' racing lines and car choice
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.
