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 · Pure Mechanics
The Guitar Hero entry that added drums and vocals to chase full-band play.
Crash Bandicoot leans Execution (Pure Mechanics); Guitar Hero: World Tour 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.
Crash Bandicoot
Tight jumps on narrow paths punish slop
Guitar Hero: World Tour
Fret-and-strum accuracy on expert note charts
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
Guitar Hero: World Tour
Charts never adapt
Crash Bandicoot leans a little harder on variance, though the gap is small.

Crash Bandicoot
Box routes and gem requirements are learnable
Guitar Hero: World Tour
Star power activation paths drive top scores
