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
Fifth-generation reboot with an entirely new monster roster and stronger story.

Optimization · Pure Optimization
Scheduling training, decay and skill counters in a solvable management loop.
Pokémon Black leans Optimization (Pure Optimization); Punch Club leans Optimization (Pure Optimization).
Punch Club leans a little harder on execution, though the gap is small.
Pokémon Black
Menu battles, zero reflex demand
Punch Club
Fights resolve automatically; you never throw a punch
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Pokémon Black
Story trainers follow fixed logic
Punch Club
Opponents are stat blocks with fixed styles, not minds
Punch Club leans a little harder on variance, though the gap is small.
Pokémon Black
Encounter and damage-roll randomness
Punch Club
Fight dice rolls and event pop-ups add noise
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Pokémon Black
All-new dex forces fresh team optimization
Punch Club
Stat decay scheduling and skill-tree counters are the entire game
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.
