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 · Pure Mechanics
Cover-shooter aim and QTE timing through scripted film setpieces.

Execution · Competitive PvP
Simple-input arena fighting decided by baiting human defensive resources.
James Bond 007: Quantum of Solace leans Execution (Pure Mechanics); Naruto Shippuden: Ultimate Ninja Storm Revolution leans Execution (Competitive PvP).
James Bond 007: Quantum of Solace leans a little harder on execution, though the gap is small.
James Bond 007: Quantum of Solace
Cover shooting and quick-time events run on aim and timing
Naruto Shippuden: Ultimate Ninja Storm Revolution
Combo and counter timing on intentionally simple inputs
Naruto Shippuden: Ultimate Ninja Storm Revolution leans a little harder on reads, though the gap is small.
James Bond 007: Quantum of Solace
Multiplayer adds modest human prediction; campaign is scripted
Naruto Shippuden: Ultimate Ninja Storm Revolution
Baiting a human's substitutions and guard breaks matters
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
James Bond 007: Quantum of Solace
Setpiece encounters repeat identically
Naruto Shippuden: Ultimate Ninja Storm Revolution
Fully visible fights with nothing hidden
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
James Bond 007: Quantum of Solace
Weapon choice and cover routes are shallow systems
Naruto Shippuden: Ultimate Ninja Storm Revolution
Team and awakening type picks are a shallow solvable layer
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.
