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
A punishing rally sim where commitment at speed and smart service-park decisions decide the leaderboard.

Execution · Pure Mechanics
A rally sim where split-second car control meets imperfect road information on every stage.
DiRT Rally 2.0 leans Execution (Pure Mechanics); EA Sports WRC 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.
DiRT Rally 2.0
Millimetre steering corrections at speed define stage time
EA Sports WRC
Rally pace notes demand instant throttle and wheel response
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
DiRT Rally 2.0
Solo time-attack format; no adaptive opponent
EA Sports WRC
Solo stage racing; no opponent to model
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
DiRT Rally 2.0
Hidden surface cuts, gravel buildup and weather are unmappable mid-stage
EA Sports WRC
Road surface changes and unseen cuts create real hidden unknowns
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
DiRT Rally 2.0
Car setup and service-park tyre choices are fully solvable pre-stage
EA Sports WRC
Car setup, tyre compound choice and stage routing are 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.
