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
High-speed bike control and combat timing over memorised courses.
DOOM (2016) leans Execution (Pure Mechanics); Road Rash 3 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.
Road Rash 3
High-speed steering plus melee timing against rival riders
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.
Road Rash 3
AI riders follow patterns, not adaptive minds
Road Rash 3 leans a little harder on variance, though the gap is small.
DOOM (2016)
Minimal encounter randomness.
Road Rash 3
Traffic and rival behaviour inject mild chaos
DOOM (2016) leans a little harder on optimization, though the gap is small.
DOOM (2016)
Rune and weapon mod picks meaningful.
Road Rash 3
Bike upgrades and track knowledge compound across the career
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.
