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

Execution · Practiced Mastery
Coordinating two-man cover tactics and aggro swaps through scripted firefights.

Optimization · Practiced Mastery
A squad-tactics WWII shooter built on authentic fire-and-flank maneuvers in Normandy.
Army of Two: The 40th Day leans Execution (Practiced Mastery); Brothers in Arms: Road to Hill 30 leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Army of Two: The 40th Day
Cover shooting needs competent aim but generous systems forgive
Brothers in Arms: Road to Hill 30
Aiming matters but suppression mechanics soften it
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Army of Two: The 40th Day
Enemy AI is scripted, co-op partner cooperates rather than opposes
Brothers in Arms: Road to Hill 30
German AI holds scripted positions
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Army of Two: The 40th Day
Encounters are scripted with minor spawn unknowns first time
Brothers in Arms: Road to Hill 30
Some shot and AI noise
Brothers in Arms: Road to Hill 30 leans a little harder on optimization, though the gap is small.
Army of Two: The 40th Day
Aggro management and weapon upgrades reward planned coordination
Brothers in Arms: Road to Hill 30
Fix-and-flank squad tactics are the core puzzle
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.
