head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Reads · Mind & Math
Objective-driven MOBA with shared team XP.

Optimization · Mind & Math
An economy-scaling war of build orders, scouting and multi-planet attention.
Heroes of the Storm leans Reads (Mind & Math); Planetary Annihilation leans Optimization (Mind & Math).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Heroes of the Storm
Skillshots and rotations require hands
Planetary Annihilation
Multi-planet macro demands relentless APM and attention splitting
Heroes of the Storm leans a little harder on reads, though the gap is small.
Heroes of the Storm
Team-fight cooldown trading is prediction
Planetary Annihilation
Scouting and out-guessing a human's expansion plan matters constantly
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Heroes of the Storm
Map objectives and merc camps vary
Planetary Annihilation
Procedural systems and fog hide early information
Planetary Annihilation leans a little harder on optimization, though the gap is small.
Heroes of the Storm
Talent picks and team comps deep
Planetary Annihilation
Economy scaling and build orders dominate - near-solvable openings
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.
