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

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

Optimization · Practiced Mastery
Progressing through a contaminated open world by solving its scenario tech tree and optimising base builds.
Dave the Diver leans Optimization (Pure Optimization); Once Human leans Optimization (Practiced Mastery).
Once Human leans a little harder on execution, though the gap is small.
Dave the Diver
harpoon aiming and sushi-service minigames
Once Human
Third-person shooting and dodge rolls require real aim and timing
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
Once Human
Deviant creatures follow scripted attack patterns only
Once Human leans a little harder on variance, though the gap is small.
Dave the Diver
daily fish spawns and sea changes vary
Once Human
Deviant spawn composition and loot tables carry meaningful randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dave the Diver
restaurant economy and gear upgrades drive progress
Once Human
Scenario tech tree, base construction, and gear crafting are solvable
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.
