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
An action-hack-and-slash game centered on combo execution against scripted foes.

Execution · Pure Mechanics
Spectacle hack-and-slash where reflexes and combo flow drive every fight.
BloodRayne 2 leans Execution (Practiced Mastery); God of War III leans Execution (Pure Mechanics).
God of War III leans a little harder on execution, though the gap is small.
BloodRayne 2
combo-based melee and dodge timing
God of War III
Combo execution and QTE timing carry combat.
God of War III leans a little harder on reads, though the gap is small.
BloodRayne 2
enemies run fixed attack scripts
God of War III
Bosses fully scripted spectacle.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
BloodRayne 2
minor damage/drop randomness
God of War III
Almost no randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
BloodRayne 2
upgrade path and combo optimization
God of War III
Upgrade paths short and obvious.
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.
