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
Ground-based Homeworld prequel about terrain-driven desert fleet warfare.

Optimization · Pure Optimization
Managing galactic economy and fleet counters, with prediction mattering against humans.
Homeworld: Deserts of Kharak leans Optimization (Pure Optimization); Star Wars: Empire at War leans Optimization (Pure Optimization).
Homeworld: Deserts of Kharak leans a little harder on execution, though the gap is small.
Homeworld: Deserts of Kharak
Dune-line positioning micro under fire
Star Wars: Empire at War
Some battle micro, but APM never dominates outcomes
Star Wars: Empire at War leans a little harder on reads, though the gap is small.
Homeworld: Deserts of Kharak
Human opponents in ranked skirmish
Star Wars: Empire at War
Multiplayer galactic feints and fleet composition mind-games matter
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Homeworld: Deserts of Kharak
Sensor range hides enemy movements
Star Wars: Empire at War
Fog of war hides enemy fleets until scouted
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Homeworld: Deserts of Kharak
Terrain elevation and carrier economy are the core test
Star Wars: Empire at War
Economy, tech order and counter-unit composition decide campaigns
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.
