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 · Practiced Mastery
Tests handheld drift-racing execution on short memorisable circuits.
Need for Speed: Hot Pursuit 2 leans Execution (Practiced Mastery); Sonic Drift 2 leans Execution (Practiced Mastery).
Need for Speed: Hot Pursuit 2 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
Sonic Drift 2
Drift timing on tiny Game Gear tracks decides 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
Sonic Drift 2
AI racers follow fixed lines; link-cable duels are rare
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Need for Speed: Hot Pursuit 2
Cop spawns and traffic add mild run-to-run noise
Sonic Drift 2
Item pickups add mild race randomness
Need for Speed: Hot Pursuit 2 leans a little harder on optimization, though the gap is small.
Need for Speed: Hot Pursuit 2
Track knowledge and racing lines are learnable and fixed
Sonic Drift 2
Character choice and track lines have learnable optima
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.
