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
Experimenting with doll abilities to uncover multiple solutions to fixed puzzles.

Optimization · Pure Optimization
Patience-driven crop scheduling and token economics in a browser farm.
Stacking leans Optimization (Pure Optimization); Sunflower Land 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.
Stacking
Hopping between dolls requires no dexterity
Sunflower Land
Clicking crops requires no dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Stacking
Puzzle NPCs are static props, not minds
Sunflower Land
No adaptive opponent in farming loops
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Stacking
Doll abilities are hidden until tried once
Sunflower Land
Market prices and seasonal events add modest unknowns
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Stacking
Finding every solution per puzzle is the real challenge
Sunflower Land
Crop timing, resource chains and trade economics 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.
