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
Pure car control over loose surfaces, sharpened by memorising every stage.

Execution · Practiced Mastery
The current entry in the officially licensed Formula 1 racing simulation series.
Colin McRae Rally 2.0 leans Execution (Pure Mechanics); F1 25 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.
Colin McRae Rally 2.0
Surface-specific car control at speed decides every stage
F1 25
precise braking, throttle, and racing lines
F1 25 leans a little harder on reads, though the gap is small.
Colin McRae Rally 2.0
Time-trial format - no adaptive opponent on the stage
F1 25
minor multiplayer positioning reads
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Colin McRae Rally 2.0
Mid-stage surprises minimal once pace notes are internalised
F1 25
weather and safety-car randomness
F1 25 leans a little harder on optimization, though the gap is small.
Colin McRae Rally 2.0
Memorising stages and tuning setups converges times steadily
F1 25
strategy, tire, and setup optimization
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.
