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
Retro arcade racer channeling Top Gear's pure lane-weaving speed.
F-Zero leans Execution (Pure Mechanics); Horizon Chase Turbo 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
Horizon Chase Turbo
Weaving through traffic and nailing fuel pickups
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
Horizon Chase Turbo
Rival cars run fixed rubber-band logic
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
Horizon Chase Turbo
Minimal randomness in track layouts
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
Horizon Chase Turbo
Car stats and lap memorization help
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.
