Building comparison
head to head
ARMSvsSuper Smash Bros.
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Axis by axis
Execution6 vs 7
Super Smash Bros. leans a little harder on execution, though the gap is small.
ARMS
Curving punches and dodge timing
Super Smash Bros.
Z-cancels and DI demand fast precise inputs despite simple controls.
Reads7 vs 7
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
ARMS
Whiff-punish games against adapting humans
Super Smash Bros.
Edgeguard and tech-chase guessing against adapting humans decides stocks.
Variance2 vs 2
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
ARMS
Minor stage and item randomness
Super Smash Bros.
Item spawns add randomness; tournament rules strip most of it.
Optimization4 vs 4
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
ARMS
Arm loadout counters and matchup study
Super Smash Bros.
Stage positioning and percent-based kill setups are learnable.
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.
