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

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

Hearts of Iron IV
focus tree branches, events
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
A Total War Saga: Troy
deep economy, tech, and battle-formation mastery
Hearts of Iron IV
division templates and production solved
