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
A calendar-driven JRPG carried by persona fusion and social-link planning.

Optimization · Pure Optimization
A streamlined Kanto remake blending classic battles with Pokemon GO-style motion-throw catching.
Persona 4 Golden leans Optimization (Pure Optimization); Pokemon: Let's Go, Pikachu! leans Optimization (Pure Optimization).
Pokemon: Let's Go, Pikachu! leans a little harder on execution, though the gap is small.
Persona 4 Golden
Turn-based, no input demand
Pokemon: Let's Go, Pikachu!
Motion-controlled ball throws add light timing skill
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Persona 4 Golden
Scripted enemies
Pokemon: Let's Go, Pikachu!
Trainers are scripted; minimal PvP focus
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Persona 4 Golden
Weakness and crit rolls
Pokemon: Let's Go, Pikachu!
Catch rolls and wild spawns bring luck
Persona 4 Golden leans a little harder on optimization, though the gap is small.
Persona 4 Golden
Persona fusion and calendar routing rewarded
Pokemon: Let's Go, Pikachu!
