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
Movement-heavy shooting where map control and reading enemy pushes decide matches.
Awesomenauts leans Execution (Grand Arena); Splatoon 3 leans Execution (Competitive PvP).
Splatoon 3 leans a little harder on execution, though the gap is small.
Awesomenauts
Platforming aim and skillshots reward dexterity.
Splatoon 3
Aim, squid movement and ink mobility decide engagements
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 3
Turf and ranked battles hinge on predicting adapting human squads
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 3
Matchmaking and special timing add modest noise
Awesomenauts leans a little harder on optimization, though the gap is small.
Awesomenauts
Builds, timings, and push economy solvable.
Splatoon 3
Gear builds, weapon kits and map control patterns are studied
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.
