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 · Competitive PvP
Territory control through shooter execution and constant prediction of adapting human teams.
Awesomenauts leans Execution (Grand Arena); Splatoon leans Execution (Competitive PvP).
Splatoon leans a little harder on execution, though the gap is small.
Awesomenauts
Platforming aim and skillshots reward dexterity.
Splatoon
Aim, swim-form movement and ink management are constant demands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Awesomenauts
Human opponents adapt lanes and picks constantly.
Splatoon
Human opponents adapt flanks and pushes every match
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
Hidden squids in ink create momentary information gaps
Awesomenauts leans a little harder on optimization, though the gap is small.
Awesomenauts
Builds, timings, and push economy solvable.
Splatoon
Weapon kits, map control timing and gear builds reward study
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.
