head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Practiced Mastery
Action-RPG sequel turning Persona 5's turn battles into musou-style real-time brawls.

Optimization · Practiced Mastery
Lara raids Siberian tombs in a stealth-action adventure heavy on puzzles.
Persona 5 Strikers leans Optimization (Practiced Mastery); Rise of the Tomb Raider leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Persona 5 Strikers
Real-time musou combos and dodge timing
Rise of the Tomb Raider
Bow aim, stealth timing, and platforming sequences.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Persona 5 Strikers
Enemies swarm on scripts
Rise of the Tomb Raider
Guards follow predictable patrol scripts.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Persona 5 Strikers
Minor drop and request randomness
Rise of the Tomb Raider
Tomb unknowns dissolve after one visit.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Persona 5 Strikers
Weakness exploitation and bond skill investment
Rise of the Tomb Raider
Tomb puzzles, crafting, and collectible routing are 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.
