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 · Practiced Mastery
Managing air meter and shortcut routes at speed on memorised tracks.

Execution · Practiced Mastery
A kart racer testing cornering execution under item-driven chaos.
Sonic Riders leans Execution (Practiced Mastery); Toy Story Racer 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.
Sonic Riders
Air management, drift timing and shortcuts demand practiced hands
Toy Story Racer
Cornering lines and drift timing decide races
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Sonic Riders
Versus humans there is mild positional jockeying
Toy Story Racer
Split-screen rivals add light human prediction
Toy Story Racer leans a little harder on variance, though the gap is small.
Sonic Riders
Item and turbulence placement adds light randomness
Toy Story Racer
Item pickups shuffle positions unpredictably
Sonic Riders leans a little harder on optimization, though the gap is small.
Sonic Riders
Gear choice and shortcut routes reward track study
Toy Story Racer
Track shortcuts and item usage reward learning
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.
