Axis by axis
Execution1 vs 2
SpaceChem leans harder on execution: Drawing waldo paths requires no physical precision
Reads0 vs 0
Even - both lean on reads about the same.
Variance1 vs 0
RollerCoaster Tycoon leans harder on variance: Guest spawns and breakdowns barely matter
Optimization9 vs 10
SpaceChem leans harder on optimization: Designing correct chemical pipelines that transform inputs to outputs exactly
Two games can score the same on an axis and still test it in very different ways - read each rationale, not just the number.
