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

Execution · Pure Mechanics
A rally sim whose procedural stages keep variance alive while rewarding clean car control.

Execution · Pure Mechanics
A survival game whose difficulty comes from awkward physics-based hand control.
DiRT 4 leans Execution (Pure Mechanics); Hand Simulator: Survival 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 4
Procedural stages still demand consistent throttle and apex discipline
Hand Simulator: Survival
Clumsy fine motor control of hands is the whole joke
Hand Simulator: Survival leans a little harder on reads, though the gap is small.
DiRT 4
Time-attack structure has no adaptive opponent
Hand Simulator: Survival
Other players exist but combat is chaotic, not modeling
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
DiRT 4
Procedurally generated stages prevent full route memorisation
Hand Simulator: Survival
Physics chaos and spawns create unpredictable situations
DiRT 4 leans a little harder on optimization, though the gap is small.
DiRT 4
Car choice, setup and rally team progression are solvable systems
Hand Simulator: Survival
Crafting and survival systems reward some planning
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.
