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
Open-world racing MMO spanning a condensed United States.

Execution · Practiced Mastery
DOS-era kart racer with animal drivers flinging hedgehogs at each other.
The Crew leans Execution (Practiced Mastery); Wacky Wheels leans Execution (Practiced Mastery).
Wacky Wheels leans a little harder on execution, though the gap is small.
The Crew
car control across long cross-country races
Wacky Wheels
Cornering lines and hedgehog shots demand steady inputs.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
The Crew
PvP races involve mild positional mind games
Wacky Wheels
Split-screen rivals add light human prediction.
Wacky Wheels leans a little harder on variance, though the gap is small.
The Crew
traffic and open-world events add noise
Wacky Wheels
Item pickups and AI rubber-banding inject randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
The Crew
car specs and route choice are tunable
Wacky Wheels
Track memorization and shortcut routing converge fast.
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.
