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

Optimization · Pure Optimization

Optimization · Pure Optimization
A 2D sandbox where preparation and gear tiering carry boss fights.
Pokémon Snap leans Optimization (Pure Optimization); Terraria 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.
Pokémon Snap
Timing photos on a moving rail
Terraria
Boss fights require dodging and aim under pressure.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Pokémon Snap
Creature behavior is fully scripted
Terraria
Bosses use scripted attacks; no adaptation.
Terraria leans a little harder on variance, though the gap is small.
Pokémon Snap
Minor behavioral wiggle per run
Terraria
World seeds and loot drops randomized.
Terraria leans a little harder on optimization, though the gap is small.
Pokémon Snap
Triggering rare poses is route knowledge
Terraria
Gear progression and arena prep solve every boss.
