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 · Practiced Mastery
Tests drift-boost technique and city-route optimization against a fare timer.

Execution · Practiced Mastery
Arcade car control at speed over memorised tracks with scripted police pressure.
Crazy Taxi 3: High Roller leans Execution (Practiced Mastery); Need for Speed: Hot Pursuit 2 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.
Crazy Taxi 3: High Roller
Crazy dash and drift chains under the timer are pure technique
Need for Speed: Hot Pursuit 2
High-speed cornering and traffic dodging are the whole test
Need for Speed: Hot Pursuit 2 leans a little harder on reads, though the gap is small.
Crazy Taxi 3: High Roller
Passengers and traffic don't adapt
Need for Speed: Hot Pursuit 2
AI racers and cops follow rubber-band scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Crazy Taxi 3: High Roller
Fare spawns vary slightly run to run
Need for Speed: Hot Pursuit 2
Cop spawns and traffic add mild run-to-run noise
Crazy Taxi 3: High Roller leans a little harder on optimization, though the gap is small.
Crazy Taxi 3: High Roller
Map routes and shortcut knowledge separate scores
Need for Speed: Hot Pursuit 2
Track knowledge and racing lines are learnable and fixed
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.
