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

Optimization · Pure Optimization
Stylish JRPG where phantom thieves steal hearts on a tightly optimized school calendar.

Optimization · Pure Optimization
Open-world Pokémon where you tackle gyms and titans in any order.
Persona 5 leans Optimization (Pure Optimization); Pokémon Scarlet leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Persona 5
Stylish menus, not reflexes
Pokémon Scarlet
Open-world traversal, battles stay menu-based
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Persona 5
Palace enemies use fixed weaknesses
Pokémon Scarlet
NPC trainers never adapt
Persona 5 leans a little harder on variance, though the gap is small.
Persona 5
Fusion alerts and negotiation rolls
Pokémon Scarlet
Open-world spawns and tera raids
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Persona 5
Confidant calendar routing and baton-pass weakness chains
Pokémon Scarlet
Terastallize typing adds a planning 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.
