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

Variance · Systems & Chaos
Short procedural co-op runs where mapping event outcomes outweighs combat skill.

Optimization · Practiced Mastery
Routing efficient digs and upgrades through a randomised mine.
Moon Hunters leans Variance (Systems & Chaos); SteamWorld Dig leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Moon Hunters
Light action combat with simple dodge timing
SteamWorld Dig
Digging and platforming need modest precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Moon Hunters
No adaptive opponent in co-op myth-building
SteamWorld Dig
Enemies follow simple fixed patterns
Moon Hunters leans a little harder on variance, though the gap is small.
Moon Hunters
Procedural maps and event rolls reshape each short run
SteamWorld Dig
Randomised mine layouts hide ore and hazards each run
SteamWorld Dig leans a little harder on optimization, though the gap is small.
Moon Hunters
Personality builds and event outcomes map over replays
SteamWorld Dig
Upgrade routing and efficient dig paths drive 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.
