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.

Optimization · Practiced Mastery
Action-adventure about a photojournalist exposing an alien conspiracy with stealth and a camera.

Optimization · Practiced Mastery
A physics hide-and-seek testing systematic search efficiency room by room.
Beyond Good & Evil leans Optimization (Practiced Mastery); Elebits leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Beyond Good & Evil
Light combat, stealth timing, and hovercraft racing
Elebits
Pointer aiming and physics manipulation stay gentle
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Beyond Good & Evil
Guards follow fixed patrol scripts
Elebits
Elebits scatter on simple scripts, not adaptation
Elebits leans a little harder on variance, though the gap is small.
Beyond Good & Evil
First-run photo hunts and story beats
Elebits
Hiding spots are unknown until rooms are torn apart
Beyond Good & Evil leans a little harder on optimization, though the gap is small.
Beyond Good & Evil
Stealth routes, pearls economy, and puzzles
Elebits
Efficient search order and power growth drive high scores
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.
