head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

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

Execution · Practiced Mastery
Carving territory under pressure - line discipline against drifting scripted enemies.
Peak leans Execution (Practiced Mastery); Volfied 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.
Peak
Stamina-managed grip timing - one slipped input drops the whole climb
Volfied
Cutting territory while exposed punishes any slow or sloppy line
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
Volfied
Alien movement is scripted-random, not an adapting mind
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
Volfied
Enemy drift adds unpredictable danger to every cut attempt
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
Volfied
Choosing safe cut shapes and percentages is plannable
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.
