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
Stick execution and reading human opponents within a meta-driven system.

Execution · Competitive PvP
A wrestling game testing grapple timing and reversal prediction against opponents.
FIFA 18 leans Execution (Competitive PvP); WWE Day of Reckoning 2 leans Execution (Competitive PvP).
FIFA 18 leans a little harder on execution, though the gap is small.
FIFA 18
Perfect stick skill and timing dominate dribbles and finishing
WWE Day of Reckoning 2
Grapple and reversal timing windows demand precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
FIFA 18
Human opponents bait, switch tactics and counter your habits
WWE Day of Reckoning 2
Versus humans, predicting strikes and reversals is constant
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
FIFA 18
Bounce physics and pack luck add measured chaos
WWE Day of Reckoning 2
Reversal and pin outcomes carry some randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
FIFA 18
Formation, squad chemistry and meta mechanics reward study
WWE Day of Reckoning 2
Move-set knowledge and stamina management 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.
