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.

Tom Clancy's Splinter Cell: Double Agent
Balancing JBA and NSA trust is a solvable system.
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.
