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.

Optimization · Pure Optimization
Day-job hybrid of relaxed spearfishing dives and nightly sushi-bar management.

Optimization · Systems & Chaos
Racing the day cycle to stack items faster than the seed punishes you.
Dave the Diver leans Optimization (Pure Optimization); Muck leans Optimization (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Dave the Diver
harpoon aiming and sushi-service minigames
Muck
Kiting bosses and dodging demands basic action skill
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dave the Diver
no adaptive opponent
Muck
Enemies swarm on simple scripts
Muck leans a little harder on variance, though the gap is small.
Dave the Diver
daily fish spawns and sea changes vary
Muck
Seeds, chest rolls and item drops shape every run
Dave the Diver leans a little harder on optimization, though the gap is small.
Dave the Diver
restaurant economy and gear upgrades drive progress
Muck
Power-stacking economy and day-loop routing decide survival
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.
