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

Execution · Competitive PvP
WWII team shooter blending aim and squad tactics.

Execution · Pure Mechanics
Classic WWII shooter whose objective-based multiplayer defined a genre.
Battlefield V leans Execution (Competitive PvP); Return to Castle Wolfenstein leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Battlefield V
Bullet drop and recoil punish sloppy aim
Return to Castle Wolfenstein
Fast strafing and precise hitscan aim dominate duels
Battlefield V leans a little harder on reads, though the gap is small.
Battlefield V
Flanks and squad play reward map sense
Return to Castle Wolfenstein
Multiplayer objective pushes hinge on outguessing human defense
Battlefield V leans a little harder on variance, though the gap is small.
Battlefield V
Vehicle spawns and chaos create swings
Return to Castle Wolfenstein
Fixed objectives and scripted singleplayer enemies, little randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Battlefield V
Class loadouts and fortifications optimize holds
Return to Castle Wolfenstein
Objective timings, class roles, and routes reward planning
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.
