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

Execution · Practiced Mastery
An open-world cop action game mixing driving, gunplay, and martial arts across a mapped Los Angeles.
Cars 3: Driven to Win leans Execution (Practiced Mastery); True Crime: Streets of LA 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.
Cars 3: Driven to Win
drifting and item-timing control
True Crime: Streets of LA
Driving, shooting, and brawling reflexes
Cars 3: Driven to Win leans a little harder on reads, though the gap is small.
Cars 3: Driven to Win
minimal, mostly AI opponents
True Crime: Streets of LA
AI cops and crooks are scripted
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
True Crime: Streets of LA
Random street crimes pop up
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
True Crime: Streets of LA
Branching missions and upgrade routes 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.
