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.

Execution · Practiced Mastery
A family-tuned brawler-platformer testing modest timing and simple puzzle solutions.

Execution · Practiced Mastery
A cooperative puzzle-platformer rooted in Iñupiat folklore where timing and puzzle logic matter lightly.
Knack II leans Execution (Practiced Mastery); Never Alone: Kisima Ingitchuna leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Knack II
Light combo timing and platforming pitched at families
Never Alone: Kisima Ingitchuna
platforming timing with companion required
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Knack II
Enemies run simple scripts without adaptation
Never Alone: Kisima Ingitchuna
no opponents, puzzle-platformer
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Knack II
Levels are fixed with nothing hidden beyond first sight
Never Alone: Kisima Ingitchuna
minimal randomness
Knack II leans a little harder on optimization, though the gap is small.
Knack II
Size-swap puzzles have single obvious solutions
Never Alone: Kisima Ingitchuna
puzzle solutions are lightly solvable
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.
