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
A military shooter testing aim with moderate prediction of human opponents online.

Execution · Practiced Mastery
Alternate-history alien-invasion shooter known for its inventive Chimeran arsenal.
Medal of Honor: Warfighter leans Execution (Competitive PvP); Resistance: Fall of Man leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Medal of Honor: Warfighter
Gunfights reward aim in both campaign and multiplayer
Resistance: Fall of Man
Aim and weapon handling against Chimera hordes.
Medal of Honor: Warfighter leans a little harder on reads, though the gap is small.
Medal of Honor: Warfighter
Human opponents in multiplayer demand positional prediction
Resistance: Fall of Man
Sizable competitive multiplayer added genuine human opposition.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Medal of Honor: Warfighter
Spawns and engagements add modest unpredictability
Resistance: Fall of Man
Campaign unknowns on first pass.
Resistance: Fall of Man leans a little harder on optimization, though the gap is small.
Medal of Honor: Warfighter
Class loadouts and map knowledge form a thin layer
Resistance: Fall of Man
Exotic weapon selection per encounter rewards system knowledge.
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.
