Halo: Combat Evolved
Aim, grenade timing, and vehicle control
Reads3 vs 3
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

Light multiplayer prediction; campaign AI is scripted
Halo: Combat Evolved
Multiplayer duels reward reading humans

Call of Duty
Some spawn and hit unpredictability
Halo: Combat Evolved
Covenant AI varies tactics slightly

Call of Duty
Memorising set pieces and weapon positions
