head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Practiced Mastery
A top-down co-op shooter testing aim and survival against alien swarms.

Execution · Twitch Chaos
Flipper execution and table knowledge with Pokémon-catching RNG on top.
Bunch of Heroes leans Execution (Practiced Mastery); Pokémon Pinball leans Execution (Twitch Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Bunch of Heroes
Twin-stick aiming and dodging swarms is the core
Pokémon Pinball
Flipper timing and nudge control are the whole input
Bunch of Heroes leans a little harder on reads, though the gap is small.
Bunch of Heroes
Enemies swarm on scripted AI, no adaptation
Pokémon Pinball
A pinball table has no mind
Pokémon Pinball leans a little harder on variance, though the gap is small.
Bunch of Heroes
Enemy spawns and waves add some randomness
Pokémon Pinball
Ball physics and catch-mode rolls add real randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Bunch of Heroes
Upgrade and co-op positioning choices matter lightly
Pokémon Pinball
Mode routing and table knowledge raise scores predictably
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.
