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

Execution · Practiced Mastery
Simulation driving precision underpinned by setup tuning and race strategy.
NFL QB Club 2002 leans Execution (Practiced Mastery); Project CARS leans Execution (Practiced Mastery).
Project CARS leans a little harder on execution, though the gap is small.
NFL QB Club 2002
passing accuracy and timing controls are core
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.

AI defense has limited real adaptation
Project CARS
Online racecraft against humans adds light positional prediction
NFL QB Club 2002 leans a little harder on variance, though the gap is small.

play outcomes involve randomized elements
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.

playbook and roster strategy is deep
Project CARS
Setup tuning and pit strategy reward deep study
