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.

Optimization · Pure Optimization
Small-town murder-mystery JRPG balancing friendships by day and TV-world dungeons by night.

Optimization · Pure Optimization
A kingdom-management narrative where you ration gold and favors as a beleaguered king.
Persona 4 leans Optimization (Pure Optimization); Yes, Your Grace leans Optimization (Pure Optimization).
Persona 4 leans a little harder on execution, though the gap is small.
Persona 4
Menu combat; zero dexterity
Yes, Your Grace
Menu choices only
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Persona 4
Shadow bosses use scripted patterns
Yes, Your Grace
Petitioners are scripted, not adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Persona 4
Randomized dungeon floors and fusion rolls
Yes, Your Grace
Outcomes of choices hidden on first run
Persona 4 leans a little harder on optimization, though the gap is small.
Persona 4
Social link scheduling and weakness-exploit planning
Yes, Your Grace
Resource budgeting across known story beats is 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.
