head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Pure Mechanics
An off-road racer testing vehicle control over rough terrain plus freeform route choice.

Execution · Pure Mechanics
An arcade test of jump timing and enemy-flipping precision on a single screen.
1nsane leans Execution (Pure Mechanics); Mario Bros. 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.
1nsane
Wrestling physics-heavy trucks over terrain is the core skill
Mario Bros.
Precise jumps and bump timing under crowding enemies decide survival
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
1nsane
Multiplayer jostling exists but barely rewards prediction
Mario Bros.
Versus mode adds light human interference, enemies are scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
1nsane
Terrain deformation and pile-ups add run noise
Mario Bros.
Enemy spawns vary slightly but patterns are quickly learned
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
1nsane
Line choice and checkpoint routing across open terrain matter
Mario Bros.
POW block usage and enemy routing have known best lines
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.
