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

Execution · Grand Arena
A football sim testing stick execution, play-call reads, and playbook optimisation against opponents.
Battlefield 4 leans Execution (Competitive PvP); NFL 2K1 leans Execution (Grand Arena).
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
NFL 2K1
Precise stick control on passes and jukes matters
NFL 2K1 leans a little harder on reads, though the gap is small.
Battlefield 4
Human teams adapt to flanks and levolution chokes
NFL 2K1
Reading a human opponent's play-calls is central
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
NFL 2K1
Fumbles and catch outcomes add measured chaos
NFL 2K1 leans a little harder on optimization, though the gap is small.
Battlefield 4
Loadout tuning and objective rotation knowledge
NFL 2K1
Playbook knowledge and matchup exploitation reward study
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.
