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

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

Optimization · Pure Optimization
Pure stealth game about reading light and sound to ghost through guarded mansions unseen.

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
Thief: Deadly Shadows
Quiet movement and timing windows need care, not twitch
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

Thief: Deadly Shadows

Thief: Deadly Shadows leans a little harder on optimization, though the gap is small.
Dave the Diver
restaurant economy and gear upgrades drive progress
Thief: Deadly Shadows
Light, sound, and route mastery makes ghosting solvable
