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

Reads · Competitive PvP
A 3D arena fighter where extendable-arm punches curve mid-flight in PvP duels.

Execution · Competitive PvP
Football sim testing stick execution and reading a human opponent's tactical habits.
ARMS leans Reads (Competitive PvP); FIFA Soccer 11 leans Execution (Competitive PvP).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
ARMS
Curving punches and dodge timing
FIFA Soccer 11
Pass timing, dribbling and finishing demand stick skill
ARMS leans a little harder on reads, though the gap is small.
ARMS
Whiff-punish games against adapting humans
FIFA Soccer 11
Human opponents' defensive habits and attacking patterns must be modelled
FIFA Soccer 11 leans a little harder on variance, though the gap is small.
ARMS
Minor stage and item randomness
FIFA Soccer 11
Deflections and keeper behaviour add bounded chaos
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
FIFA Soccer 11
Formations, tactics and squad knowledge shape matches
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.
