Axis by axis
Execution8 vs 8
Even - both lean on execution about the same.
Reads0 vs 0
Even - both lean on reads about the same.
Variance2 vs 1
Tetris Effect leans harder on variance: Randomised bag is bounded and quickly mappable
Optimization4 vs 3
Tetris Effect leans harder on optimization: Stacking theory and Zone usage have known optimal lines
Two games can score the same on an axis and still test it in very different ways - read each rationale, not just the number.
