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

Axis by axis
Execution4 vs 4
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Terraria
Boss fights require dodging and aim under pressure.
Valheim
Block-and-parry timing matters in boss fights.
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Terraria
Bosses use scripted attacks; no adaptation.
Valheim
Enemies follow scripted AI; no adaptation.

Terraria
World seeds and loot drops randomized.
Valheim
World seed and biome layout introduce mild randomness.
Optimization8 vs 8
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Terraria
Gear progression and arena prep solve every boss.
Valheim
Gear progression and base infrastructure define progress.
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.
