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.

Optimization · Practiced Mastery
The N64 collectathon that buries five playable Kongs in collectibles.

Optimization · Practiced Mastery
Acrobatic puzzle-platformer where rewinding time turns every fatal mistake into a do-over.
Donkey Kong 64 leans Optimization (Practiced Mastery); Prince of Persia: The Sands of Time 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.
Donkey Kong 64
Moderate platforming and minigame dexterity
Prince of Persia: The Sands of Time
Acrobatic platforming chains need timing; rewind softens failure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Donkey Kong 64
Scripted bosses and enemies
Prince of Persia: The Sands of Time
Sand creatures attack on fixed cues
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Donkey Kong 64
Little randomness; secrets known once found
Prince of Persia: The Sands of Time
Rewind power removes most consequence of surprise
Donkey Kong 64 leans a little harder on optimization, though the gap is small.
Donkey Kong 64
Routing five Kongs through collectible checklists
Prince of Persia: The Sands of Time
Route reading and dagger resource management solve each room
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.
