Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Pure Optimization
PS2 RPG pairing randomized dungeon crawls with rebuilding ruined towns.

Optimization · Pure Optimization
Day-job hybrid of relaxed spearfishing dives and nightly sushi-bar management.
Dark Cloud leans Optimization (Pure Optimization); Dave the Diver 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.
Dark Cloud
real-time dungeon combat with weapon timing
Dave the Diver
harpoon aiming and sushi-service minigames
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

Dave the Diver

Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dark Cloud
randomized dungeon floors and drops
Dave the Diver
daily fish spawns and sea changes vary
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dark Cloud
weapon evolution and town-building reward planning
Dave the Diver
restaurant economy and gear upgrades drive progress
