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 · Competitive PvP
Stick-skill football where beating a human means out-predicting their habits.

Execution · Competitive PvP
Sony's mascot brawler where only Super attacks score kills, making meter management the whole game.
FIFA 14 leans Execution (Competitive PvP); PlayStation All-Stars Battle Royale leans Execution (Competitive PvP).
FIFA 14 leans a little harder on execution, though the gap is small.
FIFA 14
First-touch timing, dribbling and finishing are mechanical skill
PlayStation All-Stars Battle Royale
Combo routes into Super meter need decent but modest hands.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
FIFA 14
Online opponents adapt their defending and attacking patterns
PlayStation All-Stars Battle Royale
Super-only kills make baiting human opponents the core decision.
FIFA 14 leans a little harder on variance, though the gap is small.
FIFA 14
Deflections, refs and ball physics add match-level chaos
PlayStation All-Stars Battle Royale
Items and four-player chaos add mild randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
FIFA 14
Formations, squad building and meta tactics sit underneath
PlayStation All-Stars Battle Royale
Meter-build efficiency per character is the solvable layer.
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.
