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

Optimization · Pure Optimization
Scheduling and production-chain planning in a workshop economy with light combat.

Optimization · Pure Optimization
CD Projekt's first RPG, a dark fantasy of monster contracts and morally gray choices.
My Time at Sandrock leans Optimization (Pure Optimization); The Witcher 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.
My Time at Sandrock
Light action combat never gates progress seriously
The Witcher
Rhythm-click combat needs only loose timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
My Time at Sandrock
Townsfolk and monsters run fixed routines
The Witcher
Enemies follow fixed styles and weaknesses
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
My Time at Sandrock
Some gathering randomness, quickly mapped
The Witcher
Some unknown quest outcomes on first play
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
My Time at Sandrock
Workshop production chains, scheduling and commissions are the game
The Witcher
Signs, potions, and style matchups form the real game
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.
