head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Pure Mechanics
Throttle and counter-steer precision on loose surfaces against the clock.

Execution · Pure Mechanics
A snowboarding sim testing precise trick execution and line memorization.
Colin McRae: Dirt 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.
Colin McRae: Dirt
Car control on loose surfaces is the entire test
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.
Colin McRae: Dirt
Racing the clock or AI lines, nothing adapts
Shredders
Mostly solo/coop, no adaptive opponent to predict
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Colin McRae: Dirt
Surface grip and damage add mild run noise
Shredders
Slope conditions fixed, little randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Colin McRae: Dirt
Setup tuning and corner-line knowledge underpin pace
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.
