head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, 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 runner platformer where you rotate gravity around endless tunnels of crumbling tiles.
F-Zero leans Execution (Pure Mechanics); Run 3 leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
F-Zero
Tight cornering at speed with punishing walls
Run 3
Fast gravity-rotating platforming is a pure hands test.
F-Zero leans a little harder on reads, though the gap is small.
F-Zero
AI racers don't adapt
Run 3
No opponents in the tunnels.
Run 3 leans a little harder on variance, though the gap is small.
F-Zero
Fixed tracks
Run 3
Infinite mode tiles randomize lightly.
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
Run 3
Character choice and route lines 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.
