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
A one-button Kirby racer whose chaotic City Trial mode became a cult multiplayer favourite.

Drift control while aiming weapons
Kirby Air Ride
Charge-boost timing and machine handling
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
