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
Precision 3D platformer of narrow corridors, crates, and unforgiving jumps.

Execution · Practiced Mastery
The 32-bit X series highlight where Zero becomes fully playable with his own saber-based campaign.
Crash Bandicoot leans Execution (Pure Mechanics); Mega Man X4 leans Execution (Practiced Mastery).
Crash Bandicoot leans a little harder on execution, though the gap is small.
Crash Bandicoot
Tight jumps on narrow paths punish slop
Mega Man X4
Dash-jump mobility and Zero's saber combos test hands
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 X4
Mavericks follow fixed scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Crash Bandicoot
Everything scripted and placed
Mega Man X4
Upgrade capsule locations hidden initially
Mega Man X4 leans a little harder on optimization, though the gap is small.
Crash Bandicoot
Box routes and gem requirements are learnable
Mega Man X4
Armor parts, weakness order, and X-vs-Zero routing
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.
