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.

Reads · Mind & Math
Objective-driven MOBA with shared team XP.
Awesomenauts leans Execution (Grand Arena); Heroes of the Storm leans Reads (Mind & Math).
Awesomenauts leans a little harder on execution, though the gap is small.
Awesomenauts
Platforming aim and skillshots reward dexterity.
Heroes of the Storm
Skillshots and rotations require hands
Heroes of the Storm leans a little harder on reads, though the gap is small.
Awesomenauts
Human opponents adapt lanes and picks constantly.
Heroes of the Storm
Team-fight cooldown trading is prediction
Heroes of the Storm leans a little harder on variance, though the gap is small.
Awesomenauts
Small map and shop randomness.
Heroes of the Storm
Map objectives and merc camps vary
Heroes of the Storm leans a little harder on optimization, though the gap is small.
Awesomenauts
Builds, timings, and push economy solvable.
Heroes of the Storm
Talent picks and team comps deep
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.
