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

Oriental Empires
Turn-based commands need no twitch precision
Oriental Empires leans a little harder on reads, though the gap is small.
Empire: Total War
Multiplayer line-battle feints exist
Oriental Empires

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

Campaign AI and battle dice noise
Oriental Empires
Combat and event randomness, mostly bounded
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Empire: Total War
Campaign economy and line-infantry tactics are mappable
Oriental Empires
Economy, tech, and army development decide empires
