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.

Reads · Grand Arena
Cold-front sequel; same reads-heavy tactical RTS feel.

Optimization · Mind & Math
Age-spanning RTS where city caps, territory borders, and tech-age races combine economics with military pressure.
Company of Heroes 2 leans Reads (Grand Arena); Rise of Nations leans Optimization (Mind & Math).
Company of Heroes 2 leans a little harder on execution, though the gap is small.
Company of Heroes 2
squad micro under pressure
Rise of Nations
Rare great-wonder timing and military grouping need some precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Company of Heroes 2
1v1 flanks and feints
Rise of Nations
Opponent nation pick and age-rush timing must be predicted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Company of Heroes 2
true sight, fog, weather
Rise of Nations
Map resource placement and wonder race timing add moderate uncertainty
Rise of Nations leans a little harder on optimization, though the gap is small.
Company of Heroes 2
commander and build paths solved
Rise of Nations
Territory cap optimization and age-advancement sequencing 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.
