head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Reads · Competitive PvP
Asymmetric horror PvP where four survivors out-think one human killer.

Execution · Competitive PvP
Chaotic asymmetric rounds testing aim, facility knowledge and reading untrustworthy humans.
Dead by Daylight leans Reads (Competitive PvP); SCP: Secret Laboratory leans Execution (Competitive PvP).
SCP: Secret Laboratory leans a little harder on execution, though the gap is small.
Dead by Daylight
chase loops, skill checks, and 360 dodges
SCP: Secret Laboratory
Gunfights and SCP chases demand aim and movement
Dead by Daylight leans a little harder on reads, though the gap is small.
Dead by Daylight
killer-survivor mind games never stop adapting
SCP: Secret Laboratory
Human teams bluff, betray and negotiate constantly
SCP: Secret Laboratory leans a little harder on variance, though the gap is small.
Dead by Daylight
map, perk, and pallet RNG shapes each trial
SCP: Secret Laboratory
Random spawns, items and facility layout each round
Dead by Daylight leans a little harder on optimization, though the gap is small.
Dead by Daylight
perk builds and loop routes are studied
SCP: Secret Laboratory
Class knowledge, keycard routes and zone control reward mastery
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.
