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.

Optimization · Pure Optimization
A disaster-survival strategy game managing global catastrophes.

Optimization · Pure Optimization
Side-on turn-based tactics where you manually aim ricocheting bullets for a steambot pirate crew.
Geostorm leans Optimization (Pure Optimization); SteamWorld Heist leans Optimization (Pure Optimization).
SteamWorld Heist leans a little harder on execution, though the gap is small.
Geostorm
minor reaction to disaster events
SteamWorld Heist
Manual aim and ricochet shots reward steady hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Geostorm
no adaptive opponent present
SteamWorld Heist
Enemy bots follow fixed behaviors
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Geostorm
randomized disaster events and outcomes
SteamWorld Heist
Procedural ship layouts and loot drops
SteamWorld Heist leans a little harder on optimization, though the gap is small.
Geostorm
resource and defense system management
SteamWorld Heist
Crew builds, weapon picks, and turn routing carry runs
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.
