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
An open sandbox where mastering crafting and building systems dominates over any physical skill.

Optimization · Pure Optimization
A drug-empire logistics puzzle - recipes, pricing and supply chains to optimise.
Minecraft: Java Edition leans Optimization (Pure Optimization); Schedule I 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.
Minecraft: Java Edition
barely relevant, building/PvP negligible for most
Schedule I
First-person mixing and dealing chores, low dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Minecraft: Java Edition
no adaptive opponent, sandbox play
Schedule I
Police and customers run mappable scripted routines
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Minecraft: Java Edition
world gen and mob spawns randomized
Schedule I
Customer demands and busts add light randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Minecraft: Java Edition
redstone, base/resource routing solvable systems
Schedule I
Product recipes, pricing and empire logistics are the 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.
