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
Twitch reactions and memorised lines through fast scripted obstacle courses.
DOOM (2016) leans Execution (Pure Mechanics); Tron Run/r 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.
Tron Run/r
High-speed running, jumping and disc throws under relentless pacing
DOOM (2016) leans a little harder on reads, though the gap is small.
DOOM (2016)
Demons scripted attack patterns.
Tron Run/r
Obstacle streams are scripted, not an adapting mind
Tron Run/r leans a little harder on variance, though the gap is small.
DOOM (2016)
Minimal encounter randomness.
Tron Run/r
Stream mode shuffles segments but each piece is learnable
DOOM (2016) leans a little harder on optimization, though the gap is small.
DOOM (2016)
Rune and weapon mod picks meaningful.
Tron Run/r
Score chains reward memorising layouts and optimal lines
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.
