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 · Pure Mechanics
Rhythm game where clicking circles to the beat becomes an athletic discipline.

Execution · Pure Mechanics
DS stylus rhythm game where a male cheer squad saves lives through perfectly timed taps.
osu! leans Execution (Pure Mechanics); Osu! Tatakae! Ouendan leans Execution (Pure Mechanics).
osu! leans a little harder on execution, though the gap is small.
osu!
Pixel-perfect cursor aim and tapping at extreme speeds
Osu! Tatakae! Ouendan
Stylus tap, drag, and spin precision at high tempo
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
osu!
No opponent interaction in scoring
Osu! Tatakae! Ouendan
Charts never adapt
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
osu!
Beatmaps are fully deterministic
Osu! Tatakae! Ouendan
Fully fixed note placements
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
osu!
Mod choices and map selection for ranking
Osu! Tatakae! Ouendan
Memorizing layouts matters less than stylus accuracy
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.
