head to head
Call of Duty: Modern Warfare 2 asks more than Dead by Daylight, and the gap is execution.

Execution · Competitive PvP
Blockbuster 2009 sequel famous for killstreak chains and frantic multiplayer.

Reads · Competitive PvP
Asymmetric horror PvP where four survivors out-think one human killer.
Call of Duty: Modern Warfare 2 leans Execution (Competitive PvP); Dead by Daylight leans Reads (Competitive PvP).
Call of Duty: Modern Warfare 2 leans clearly harder on execution.
Call of Duty: Modern Warfare 2
Fast time-to-kill rewards raw aim and reflex
Dead by Daylight
chase loops, skill checks, and 360 dodges
Dead by Daylight leans a little harder on reads, though the gap is small.
Call of Duty: Modern Warfare 2
Outguessing human rotations and flanks
Dead by Daylight
killer-survivor mind games never stop adapting
Dead by Daylight leans a little harder on variance, though the gap is small.
Call of Duty: Modern Warfare 2
Spawn flips and killstreak randomness
Dead by Daylight
map, perk, and pallet RNG shapes each trial
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty: Modern Warfare 2
Killstreak economy, loadout and map knowledge
Dead by Daylight
perk builds and loop routes are studied
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.
