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.

Execution · Practiced Mastery
The stealth-brawler that defined rhythmic freeflow combat and predator rooms.

Execution · Practiced Mastery
An action adventure rewarding combat timing against scripted boss patterns.
Batman: Arkham Asylum leans Execution (Practiced Mastery); God of War Ragnarok leans Execution (Practiced Mastery).
God of War Ragnarok leans a little harder on execution, though the gap is small.
Batman: Arkham Asylum
Freeflow combo timing rewards rhythm.
God of War Ragnarok
Parry timing and combo execution in combat
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Batman: Arkham Asylum
Thug AI scripted and mappable.
God of War Ragnarok
Bosses use fixed movesets
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Batman: Arkham Asylum
Encounters deterministic.
God of War Ragnarok
Negligible randomness
God of War Ragnarok leans a little harder on optimization, though the gap is small.
Batman: Arkham Asylum
Predator room routes and gadgets solvable.
God of War Ragnarok
Build choices and moveset mastery solve bosses
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.
