head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

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

Execution · Pure Mechanics
A snowboarding sim testing precise trick execution and line memorization.
DOOM (2016) leans Execution (Pure Mechanics); Shredders leans Execution (Pure Mechanics).
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.
Shredders
Precise trick timing, balance and landing control dominate
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.
Shredders
Mostly solo/coop, no adaptive opponent to predict
Shredders leans a little harder on variance, though the gap is small.
DOOM (2016)
Minimal encounter randomness.
Shredders
Slope conditions fixed, little randomness
DOOM (2016) leans a little harder on optimization, though the gap is small.
DOOM (2016)
Rune and weapon mod picks meaningful.
Shredders
Learning lines and trick combos for score routes
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.
