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

Optimization · Pure Optimization
A 4X strategy game testing empire economy, tech, and military planning.

Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.

no real-time physical skill needed
Oriental Empires
Turn-based commands need no twitch precision
Oriental Empires leans a little harder on reads, though the gap is small.
Might & Magic: Heroes VI
predicting human opponent strategy in PvP
Oriental Empires

Might & Magic: Heroes VI leans a little harder on variance, though the gap is small.

Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

army building and economy near-solvable
Oriental Empires
Economy, tech, and army development decide empires
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.
