Axis by axis
Execution6 vs 7
Halo: Reach leans harder on execution: DMR precision and armour-ability timing
Reads4 vs 4
Even - both lean on reads about the same.
Variance3 vs 2
Backbreaker leans harder on variance: Physics-driven tackles add emergent unpredictability
Optimization5 vs 5
Even - both lean on optimization about the same.
Two games can score the same on an axis and still test it in very different ways - read each rationale, not just the number.
