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

Execution · Practiced Mastery
A bubble-matching puzzle testing aim and chain planning under random bubble draws.

Execution · Practiced Mastery
Careful climbing execution and route planning where a single mistimed grab undoes everything.
Bust-A-Move Universe leans Execution (Practiced Mastery); Peak 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.
Bust-A-Move Universe
Aiming bubble shots quickly under rising pressure
Peak
Stamina-managed grip timing - one slipped input drops the whole climb
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Bust-A-Move Universe
Solo puzzle, no opponent to predict
Peak
Co-op against a mountain, no adaptive opponent
Bust-A-Move Universe leans a little harder on variance, though the gap is small.
Bust-A-Move Universe
Next bubble colors are randomized
Peak
Daily map rotation and item spawns shuffle each ascent
Bust-A-Move Universe leans a little harder on optimization, though the gap is small.
Bust-A-Move Universe
Bank-shot planning and chain setups reward strategy
Peak
Routing the wall and rationing items decides summit attempts
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.
