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
Side-on turn-based tactics where you manually aim ricocheting bullets for a steambot pirate crew.

Optimization · Pure Optimization
CD Projekt's first RPG, a dark fantasy of monster contracts and morally gray choices.
SteamWorld Heist leans Optimization (Pure Optimization); The Witcher leans Optimization (Pure Optimization).
SteamWorld Heist leans a little harder on execution, though the gap is small.
SteamWorld Heist
Manual aim and ricochet shots reward steady hands
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.
SteamWorld Heist
Enemy bots follow fixed behaviors
The Witcher
Enemies follow fixed styles and weaknesses
SteamWorld Heist leans a little harder on variance, though the gap is small.
SteamWorld Heist
Procedural ship layouts and loot drops
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.
SteamWorld Heist
Crew builds, weapon picks, and turn routing carry runs
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.
