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

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

Execution · Pure Mechanics
The stylish PS1 arcade racer with a grand prix story and a legendary soundtrack.
Colin McRae Rally 2.0 leans Execution (Pure Mechanics); R4: Ridge Racer Type 4 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.

Surface-specific car control at speed decides every stage
R4: Ridge Racer Type 4
Grip versus drift car control rewards precise corner technique
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

Colin McRae Rally 2.0 leans a little harder on optimization, though the gap is small.
Colin McRae Rally 2.0
Memorising stages and tuning setups converges times steadily
R4: Ridge Racer Type 4
Choosing machines and mastering lines is light routing
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.
