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

Execution · Competitive PvP
Combined-arms multiplayer shooter famous for map-altering levolution moments and 64-player conquest.

Execution · Practiced Mastery
The long-running American football simulation series.
Battlefield 4 leans Execution (Competitive PvP); Madden NFL Football 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.
Battlefield 4
Gunplay, vehicle mastery, and movement under fire
Madden NFL Football
passing, running, and tackling precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Battlefield 4
Human teams adapt to flanks and levolution chokes
Madden NFL Football
human opponents disguise and read plays
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Battlefield 4
Map-altering events and spawns inject noise
Madden NFL Football
fumble and injury randomness
Madden NFL Football leans a little harder on optimization, though the gap is small.
Battlefield 4
Loadout tuning and objective rotation knowledge
Madden NFL Football
playbook and roster management depth
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.
