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
A kart-style racer about drifting and using items on family-friendly tracks.

Execution · Practiced Mastery
MMO street racing testing driving lines plus grindable car-build advantage.
Cars 3: Driven to Win leans Execution (Practiced Mastery); Need for Speed: World leans Execution (Practiced Mastery).
Need for Speed: World leans a little harder on execution, though the gap is small.
Cars 3: Driven to Win
drifting and item-timing control
Need for Speed: World
Racing lines, drift control and pursuit evasion reward clean hands
Need for Speed: World leans a little harder on reads, though the gap is small.
Cars 3: Driven to Win
minimal, mostly AI opponents
Need for Speed: World
Human rivals in lobbies add slight positional prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Cars 3: Driven to Win
item pickups and track hazard randomness
Need for Speed: World
Pursuit spawns and lobby skill add mild noise
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Cars 3: Driven to Win
vehicle upgrades and track knowledge
Need for Speed: World
Car builds, powerups and route knowledge compound advantage
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.
