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

The free fan-made Guitar Hero engine where competitive charting and scoring live on.

Execution · Pure Mechanics
Infamous climbing game where one slip of the hammer undoes hours of progress.
Clone Hero leans Execution (Pure Mechanics); Getting Over It with Bennett Foddy 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.

Community charts push fretting speed past official games
Getting Over It with Bennett Foddy
Every inch climbed is precise hammer micro-control
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Clone Hero
Charts are static
Getting Over It with Bennett Foddy
The mountain never adapts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Clone Hero
Fully deterministic
Getting Over It with Bennett Foddy
Fully deterministic physics and terrain
Clone Hero leans a little harder on optimization, though the gap is small.

Star power path calculation is a science
Getting Over It with Bennett Foddy
Route knowledge helps but cannot replace hands
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.
