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

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

Optimization · Pure Optimization
A Room-style 3D puzzle box game set in Leonardo da Vinci's workshop of intricate contraptions.
Persona 5 leans Optimization (Pure Optimization); The House of Da Vinci 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
The House of Da Vinci
Light touch manipulation of mechanisms; trivial precision.
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
The House of Da Vinci
No adaptive opposition exists.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Persona 5
Fusion alerts and negotiation rolls
The House of Da Vinci
Hidden compartments and unknown contraptions; converges after discovery.
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
The House of Da Vinci
Solving fixed clockwork mechanisms is the entire test.
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.
