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 · Pure Mechanics
A rhythm game testing pure input accuracy across one band's fixed setlist.

Execution · Pure Mechanics
Cute two-button rhythm game where everything reduces to hitting notes on beat.
Green Day: Rock Band leans Execution (Pure Mechanics); Muse Dash leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Green Day: Rock Band
Hitting note highways accurately is literally the entire game
Muse Dash
Two-lane rhythm hits at high BPM are pure hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Green Day: Rock Band
Charts never react to the player
Muse Dash
Charts never adapt
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Green Day: Rock Band
Every chart is fixed and fully visible
Muse Dash
Fully deterministic note charts
Muse Dash leans a little harder on optimization, though the gap is small.
Green Day: Rock Band
Star-power activation points add a thin strategy layer
Muse Dash
Character buffs and chart memorization help margins
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.
