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
The bigger, faster sequel doubling down on chaotic crash physics and stunt minigames.

Execution · Practiced Mastery
Arcade driving precision on memorised tracks while scripted cops chase.
FlatOut 2 leans Execution (Pure Mechanics); Need for Speed III: Hot Pursuit 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.
FlatOut 2
High-speed control amid wrecks and ragdolls
Need for Speed III: Hot Pursuit
Clean cornering at top speed is the entire skill test
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
FlatOut 2
No adaptive opposition worth modeling
Need for Speed III: Hot Pursuit
Cops and rivals run scripted rubber-band behaviour
FlatOut 2 leans a little harder on variance, though the gap is small.
FlatOut 2
Crash physics and track debris vary every race
Need for Speed III: Hot Pursuit
Traffic and cop placement vary mildly per race
Need for Speed III: Hot Pursuit leans a little harder on optimization, though the gap is small.
FlatOut 2
Track knowledge and car tuning settle into routine
Need for Speed III: Hot Pursuit
Tracks are fixed; ideal lines are fully learnable
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.
