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.

Optimization · Mind & Math
A player-driven economy and political simulation where optimal doctrine-building and reading human opponents decide outcomes.

Optimization · Mind & Math
An economic RTS where you bankrupt rival Mars corporations through market manipulation instead of guns.
EVE Online leans Optimization (Mind & Math); Offworld Trading Company 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.
EVE Online
Clicking modules demands little physical precision
Offworld Trading Company
Light APM, mostly market clicks
EVE Online leans a little harder on reads, though the gap is small.
EVE Online
Player corporations and fleet FC decisions involve deep human prediction
Offworld Trading Company
Live market PvP means modelling rival tycoons
EVE Online leans a little harder on variance, though the gap is small.
EVE Online
Market prices and intel gaps are meaningful hidden information
Offworld Trading Company
Map resource distribution varies per game
EVE Online leans a little harder on optimization, though the gap is small.
EVE Online
Industry chains, fleet doctrines, and trade routes are deeply solvable systems
Offworld Trading Company
Supply-chain math and buyout timing are deeply solvable
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.
