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

Execution · Practiced Mastery
A classic frenetic shooter that rewards fast reflexes and mastering enemy patterns.
DOOM (2016) leans Execution (Pure Mechanics); The Ultimate Doom 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.
DOOM (2016)
Aim, movement, glory-kill timing all peak.
The Ultimate Doom
twitch aim and movement drive combat
DOOM (2016) leans a little harder on reads, though the gap is small.
DOOM (2016)
Demons scripted attack patterns.
The Ultimate Doom
fixed demon patterns, no adaptation
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.
The Ultimate Doom
minor spawn and drop randomness
The Ultimate Doom leans a little harder on optimization, though the gap is small.
DOOM (2016)
Rune and weapon mod picks meaningful.
The Ultimate Doom
weapon routing and glory-kill loops 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.
