Snap aim and movement speed decide split-second gunfights
Halo 3
Precision aim and grenade-melee timing

Call of Duty: Black Ops II
Spawn flips and scorestreak chaos inject randomness
Halo 3
Equipment pickups and spawn variation
Optimization5 vs 5
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty: Black Ops II
Pick-10 classes and streak economies reward optimization
Halo 3
Power-weapon timers and map control
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.
