head to head
Splatoon 2 asks more than PlayStation All-Stars Battle Royale, and the gap is optimization.

Execution · Competitive PvP
Sony's mascot brawler where only Super attacks score kills, making meter management the whole game.

Execution · Practiced Mastery
A team shooter where aim and positioning against human opponents controls the map.
PlayStation All-Stars Battle Royale leans Execution (Competitive PvP); Splatoon 2 leans Execution (Practiced Mastery).
Splatoon 2 leans a little harder on execution, though the gap is small.
PlayStation All-Stars Battle Royale
Combo routes into Super meter need decent but modest hands.
Splatoon 2
aim and movement decide ink battles
PlayStation All-Stars Battle Royale leans a little harder on reads, though the gap is small.
PlayStation All-Stars Battle Royale
Super-only kills make baiting human opponents the core decision.
Splatoon 2
predicting human opponent positioning
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
PlayStation All-Stars Battle Royale
Items and four-player chaos add mild randomness.
Splatoon 2
weapon and map rotation randomness
Splatoon 2 leans clearly harder on optimization.
PlayStation All-Stars Battle Royale
Meter-build efficiency per character is the solvable layer.
Splatoon 2
loadout and turf strategy solvable
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.
