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
Combat racing spin-off where the Jak cast trades platforming for weaponized cars.

Execution · Practiced Mastery
Managing air meter and shortcut routes at speed on memorised tracks.
Jak X: Combat Racing leans Execution (Practiced Mastery); Sonic Riders 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.
Jak X: Combat Racing
Drift control while aiming weapons
Sonic Riders
Air management, drift timing and shortcuts demand practiced hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Jak X: Combat Racing
Versus races involve light human jockeying
Sonic Riders
Versus humans there is mild positional jockeying
Jak X: Combat Racing leans a little harder on variance, though the gap is small.
Jak X: Combat Racing
Weapon pickups randomize race swings
Sonic Riders
Item and turbulence placement adds light randomness
Sonic Riders leans a little harder on optimization, though the gap is small.
Jak X: Combat Racing
Car tuning and track shortcut knowledge
Sonic Riders
Gear choice and shortcut routes reward track study
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.
