head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Execution · Pure Mechanics
Precision 3D platformer of narrow corridors, crates, and unforgiving jumps.

Execution · Practiced Mastery
Punishing platforming execution over learnable boss orders and part builds.
Crash Bandicoot leans Execution (Pure Mechanics); Mega Man X6 leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Crash Bandicoot
Tight jumps on narrow paths punish slop
Mega Man X6
Cruel platforming and boss windows demand frame-tight inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Crash Bandicoot
Hazards are fixed patterns
Mega Man X6
Bosses are fixed pattern sets
Mega Man X6 leans a little harder on variance, though the gap is small.
Crash Bandicoot
Everything scripted and placed
Mega Man X6
The Nightmare System shuffles level hazards between runs
Mega Man X6 leans a little harder on optimization, though the gap is small.
Crash Bandicoot
Box routes and gem requirements are learnable
Mega Man X6
Weapon orders, armor parts and route knowledge are essential
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.
