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
A turn-based JRPG won through formation tactics, rune builds, and exhaustive recruit hunting.
Persona 5 leans Optimization (Pure Optimization); Suikoden V 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
Suikoden V
Menu-driven turns; inputs trivial.
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
Suikoden V
Fixed enemy scripts throughout.
Persona 5 leans a little harder on variance, though the gap is small.
Persona 5
Fusion alerts and negotiation rolls
Suikoden V
Hidden recruitment triggers and drop rolls.
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
Suikoden V
Party formations, runes, and recruitment routing solve it.
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.
