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

Execution · Practiced Mastery
Careful climbing execution and route planning where a single mistimed grab undoes everything.

Execution · Practiced Mastery
An endless runner starring Sonic and friends.
Peak leans Execution (Practiced Mastery); Sonic Runners Adventure leans Execution (Practiced Mastery).
Peak leans a little harder on execution, though the gap is small.
Peak
Stamina-managed grip timing - one slipped input drops the whole climb
Sonic Runners Adventure
precise timing jumps and dashes at speed
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Peak
Co-op against a mountain, no adaptive opponent
Sonic Runners Adventure
no adaptive opponent, solo endless runner
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Peak
Daily map rotation and item spawns shuffle each ascent
Sonic Runners Adventure
obstacle and item layouts randomized
Peak leans a little harder on optimization, though the gap is small.
Peak
Routing the wall and rationing items decides summit attempts
Sonic Runners Adventure
character and item upgrade optimization
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.
