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 · Pure Mechanics
The SNES racer that made survival at extreme speed the entire test.

Execution · Pure Mechanics
A bite-sized RC racer testing precision car control over memorised racing lines.
F-Zero leans Execution (Pure Mechanics); MotorStorm: RC leans Execution (Pure Mechanics).
F-Zero leans a little harder on execution, though the gap is small.
F-Zero
Tight cornering at speed with punishing walls
MotorStorm: RC
Tight RC handling on short tracks rewards pure car control
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
F-Zero
AI racers don't adapt
MotorStorm: RC
Mostly time-attack versus static ghosts and AI
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
F-Zero
Fixed tracks
MotorStorm: RC
Deterministic tracks, identical every lap
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
F-Zero
Boost timing and racing lines converge
MotorStorm: RC
Vehicle class choice and racing lines decide leaderboard times
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.
