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

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

Execution · Competitive PvP
Timing-based reversal duels with human mind-games layered on wrestling systems.
Battlefield 4 leans Execution (Competitive PvP); WWE '13 leans Execution (Competitive PvP).
Battlefield 4 leans a little harder on execution, though the gap is small.
Battlefield 4
Gunplay, vehicle mastery, and movement under fire
WWE '13
Reversal windows and move timing decide exchanges
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
WWE '13
Human opponents vary timing to bait reversals
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
WWE '13
Kick-out rolls and momentum swings add scripted chaos
Battlefield 4 leans a little harder on optimization, though the gap is small.
Battlefield 4
Loadout tuning and objective rotation knowledge
WWE '13
Knowing move-sets and match-type systems pays off
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.
