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

Execution · Practiced Mastery
A musou-style hack-and-slash letting players mow down hordes as One Piece characters.

Execution · Practiced Mastery
An open-world crime game where combat combos and driving skill carry the action.
One Piece: Pirate Warriors 4 leans Execution (Practiced Mastery); Sleeping Dogs leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
One Piece: Pirate Warriors 4
crowd-clearing combo execution against hordes
Sleeping Dogs
brawling and driving need timing/aim
One Piece: Pirate Warriors 4 leans a little harder on reads, though the gap is small.
One Piece: Pirate Warriors 4
enemies are scripted mobs, not adaptive
Sleeping Dogs
scripted enemy AI, no adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
One Piece: Pirate Warriors 4
minimal randomness in stage encounters
Sleeping Dogs
minor loot and traffic randomness
One Piece: Pirate Warriors 4 leans a little harder on optimization, though the gap is small.
One Piece: Pirate Warriors 4
character builds and combo routing are learnable
Sleeping Dogs
upgrade paths and mission routes 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.
