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
Arcade car control at speed over memorised tracks with scripted police pressure.

Execution · Pure Mechanics
Precision car control over learnable racing lines and braking points.
Need for Speed: Hot Pursuit 2 leans Execution (Practiced Mastery); TOCA 2: Touring Car Challenge leans Execution (Pure Mechanics).
TOCA 2: Touring Car Challenge leans a little harder on execution, though the gap is small.
Need for Speed: Hot Pursuit 2
High-speed cornering and traffic dodging are the whole test
TOCA 2: Touring Car Challenge
Perfect inputs through every corner is what wins races
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Need for Speed: Hot Pursuit 2
AI racers and cops follow rubber-band scripts
TOCA 2: Touring Car Challenge
AI drivers follow set racing lines, not your psychology
Need for Speed: Hot Pursuit 2 leans a little harder on variance, though the gap is small.
Need for Speed: Hot Pursuit 2
Cop spawns and traffic add mild run-to-run noise
TOCA 2: Touring Car Challenge
Weather shifts races slightly, otherwise deterministic
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Need for Speed: Hot Pursuit 2
Track knowledge and racing lines are learnable and fixed
TOCA 2: Touring Car Challenge
Racing lines, braking points and setups are solvable per track
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.
