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
Day-glo traversal shooter where staying on rails and walls keeps your style and survival up.
Peak leans Execution (Practiced Mastery); Sunset Overdrive 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
Sunset Overdrive
Grind-rail momentum and mid-air shooting reward clean hands
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
Sunset Overdrive
Mutant hordes are pattern-driven, never adaptive
Peak leans a little harder on variance, though the gap is small.
Peak
Daily map rotation and item spawns shuffle each ascent
Sunset Overdrive
Horde mode spawns mix things up slightly
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Peak
Routing the wall and rationing items decides summit attempts
Sunset Overdrive
Amp builds, traversal lines, and style multipliers are 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.
