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 · Grand Arena
A 2D platforming MOBA blending skillshots with live human mind games.

Execution · Practiced Mastery
A team shooter where aim and positioning against human opponents controls the map.
Awesomenauts leans Execution (Grand Arena); Splatoon 2 leans Execution (Practiced Mastery).
Splatoon 2 leans a little harder on execution, though the gap is small.
Awesomenauts
Platforming aim and skillshots reward dexterity.
Splatoon 2
aim and movement decide ink battles
Awesomenauts leans a little harder on reads, though the gap is small.
Awesomenauts
Human opponents adapt lanes and picks constantly.
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.
Awesomenauts
Small map and shop randomness.
Splatoon 2
weapon and map rotation randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Awesomenauts
Builds, timings, and push economy solvable.
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.
