head to head
Dead by Daylight asks more than Worms: Ultimate Mayhem, and the gap is reads.

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

Execution · Competitive PvP
Tests trajectory aim and turn planning against human targets amid crate luck.
Dead by Daylight leans Reads (Competitive PvP); Worms: Ultimate Mayhem leans Execution (Competitive PvP).
Worms: Ultimate Mayhem leans a little harder on execution, though the gap is small.
Dead by Daylight
chase loops, skill checks, and 360 dodges
Worms: Ultimate Mayhem
3D grenade arcs and ninja-rope control reward practiced aim
Dead by Daylight leans clearly harder on reads.
Dead by Daylight
killer-survivor mind games never stop adapting
Worms: Ultimate Mayhem
Predicting a human's target priorities shapes each turn
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dead by Daylight
map, perk, and pallet RNG shapes each trial
Worms: Ultimate Mayhem
Crate drops, wind and terrain chaos swing rounds
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dead by Daylight
perk builds and loop routes are studied
Worms: Ultimate Mayhem
Weapon economy and positioning are plannable each turn
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.
