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

Donkey Kong 64
Scripted bosses and enemies
Shadow of the Colossus

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
Shadow of the Colossus
Encounters play out nearly identically each attempt.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Donkey Kong 64
Routing five Kongs through collectible checklists
Shadow of the Colossus
