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
Combo execution and dodge timing through scripted grindhouse brawls.
BloodRayne 2 leans Execution (Practiced Mastery); Shank leans Execution (Pure Mechanics).
Shank leans a little harder on execution, though the gap is small.
BloodRayne 2
combo-based melee and dodge timing
Shank
Combo juggling and dodge timing carry every brawl
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
BloodRayne 2
enemies run fixed attack scripts
Shank
Enemies and bosses attack on fixed patterns
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
Shank
Hand-built levels with no randomness
BloodRayne 2 leans a little harder on optimization, though the gap is small.
BloodRayne 2
upgrade path and combo optimization
Shank
Weapon-swap combo routing rewards some lab work
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.
