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

Optimization · Practiced Mastery
Action RPG prequel to FFVII whose combat spins a slot machine for buffs.

Execution · Practiced Mastery
Physical VR combat plus scavenging economy management under time pressure.
Crisis Core: Final Fantasy VII leans Optimization (Practiced Mastery); The Walking Dead: Saints & Sinners leans Execution (Practiced Mastery).

real-time dodging and attack timing
The Walking Dead: Saints & Sinners
Physical VR stabs, aim and reloads under pressure are real skill
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Crisis Core: Final Fantasy VII
no adaptive opponent
The Walking Dead: Saints & Sinners
Walkers and human NPCs follow scripted behaviour
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Crisis Core: Final Fantasy VII

The Walking Dead: Saints & Sinners
Scavenging finds and encounter layouts vary per run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Crisis Core: Final Fantasy VII
materia fusion is a deep solvable system
The Walking Dead: Saints & Sinners
Crafting economy, stamina and route planning drive survival
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.
