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

Optimization · Pure Optimization
Solving fixed gravity-bending puzzles inside a deterministic nightmare.

Optimization · Pure Optimization
A first-person shop management sim about stocking shelves, setting prices and growing a small supermarket.
Darq leans Optimization (Pure Optimization); Supermarket Simulator 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.
Darq
Slow stealth walking; minimal timing demands
Supermarket Simulator
Stocking and checkout are light manual busywork.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Darq
Nightmare enemies patrol fixed scripted routes
Supermarket Simulator

Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Darq
Puzzle solutions hidden only until first discovery
Supermarket Simulator
Daily customer flow varies a little.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Darq
Gravity-bending puzzle logic is the entire test
Supermarket Simulator
Pricing margins, ordering and shelf layout drive growth.
