A Dance of Fire and Icevsosu!
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
A Dance of Fire and Ice
Execution · Pure Mechanics
Strict one-button rhythm game where two orbiting planets must hit every beat exactly.
osu!
Execution · Pure Mechanics
Rhythm game where clicking circles to the beat becomes an athletic discipline.
A Dance of Fire and Ice leans Execution (Pure Mechanics); osu! leans Execution (Pure Mechanics).

osu! leans a little harder on execution, though the gap is small.
A Dance of Fire and Ice
One-button precision timing with zero forgiveness
osu!
Pixel-perfect cursor aim and tapping at extreme speeds
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
A Dance of Fire and Ice
No opponent, just the track
osu!
No opponent interaction in scoring
Variance0 vs 0
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
A Dance of Fire and Ice
Completely deterministic patterns
osu!
Beatmaps are fully deterministic
Optimization2 vs 2
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

Mod choices and map selection for ranking
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.
