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
A spy shooter testing console aim and learning each mission's intended route.

Execution · Practiced Mastery
Cinematic treasure-hunting where set pieces outshine systems.
James Bond 007: Agent Under Fire leans Execution (Practiced Mastery); Uncharted 4: A Thief's End leans Execution (Practiced Mastery).
James Bond 007: Agent Under Fire leans a little harder on execution, though the gap is small.
James Bond 007: Agent Under Fire
Console FPS aim and rail-shooter timing carry missions
Uncharted 4: A Thief's End
Cover shooting and platforming reward timing.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
James Bond 007: Agent Under Fire
Split-screen friends add mild prediction; campaign AI is scripted
Uncharted 4: A Thief's End
Scripted enemy AI throughout.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
James Bond 007: Agent Under Fire
Missions play out identically each attempt
Uncharted 4: A Thief's End
Essentially no randomness.
James Bond 007: Agent Under Fire leans a little harder on optimization, though the gap is small.
James Bond 007: Agent Under Fire
Gadget usage and stealth routes raise mission ratings
Uncharted 4: A Thief's End
Few systems to optimize beyond difficulty.
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.
