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

Execution · Practiced Mastery
Consistent lap-time precision supported by tuning and racing-line study.

Execution · Practiced Mastery
Simulation driving precision underpinned by setup tuning and race strategy.
Forza Motorsport 7 leans Execution (Practiced Mastery); Project CARS leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Forza Motorsport 7
Braking points, throttle control and racing lines are everything
Project CARS
Braking points and wheel control at the sim limit
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Forza Motorsport 7
Online racecraft adds light human positioning play
Project CARS
Online racecraft against humans adds light positional prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Forza Motorsport 7
Dynamic weather shifts conditions mid-race
Project CARS
Dynamic weather injects some session randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Forza Motorsport 7
Tuning setups and line study reward engineering effort
Project CARS
Setup tuning and pit strategy reward deep study
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.
