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
Tower-defense math wrapped in a city-building economy to optimise.

Optimization · Pure Optimization
Stylish JRPG where phantom thieves steal hearts on a tightly optimized school calendar.
Bloons Monkey City leans Optimization (Pure Optimization); Persona 5 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.
Bloons Monkey City
Tower placement is unhurried clicking
Persona 5
Stylish menus, not reflexes
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Bloons Monkey City
Bloon waves never adapt to your defenses
Persona 5
Palace enemies use fixed weaknesses
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Bloons Monkey City
Captured tile layouts and special events vary mildly
Persona 5
Fusion alerts and negotiation rolls
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Bloons Monkey City
Tower math, city economy and unlock routing are the whole game
Persona 5
Confidant calendar routing and baton-pass weakness chains
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.
