head to head

Call of Duty: Black Ops leans Execution (Competitive PvP); Super Smash Bros. Ultimate leans Reads (Competitive PvP).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty: Black Ops
Gunfights hinge on aim and reaction speed
Super Smash Bros. Ultimate
Tech skill, edgeguards, and DI are mechanically heavy.
Super Smash Bros. Ultimate leans clearly harder on reads.
Call of Duty: Black Ops
Reading human opponents' positioning and timing
Super Smash Bros. Ultimate
Adaptive opponents drive ledge and platform mind games.
Call of Duty: Black Ops leans a little harder on variance, though the gap is small.
Call of Duty: Black Ops
Spawns, care packages, zombies RNG
Super Smash Bros. Ultimate
Stage hazards and items if enabled.
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
Class builds, map control, zombies routing
Super Smash Bros. Ultimate
Matchup knowledge and kill confirms are learnable.
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.
