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 precision-platforming metroidvania built around fluid traversal.
F-Zero leans Execution (Pure Mechanics); Ori and the Blind Forest 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
Ori and the Blind Forest
Precise platforming and bash-chain escape sequences
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
Ori and the Blind Forest
Scripted enemies, no adaptive opponent
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
Ori and the Blind Forest
Fixed layouts, minimal randomness
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
Ori and the Blind Forest
Ability routing and shard builds matter
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.
