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

Execution · Practiced Mastery
Sprawling action horror with four campaigns and a surprisingly deep combat system.
Keith Van Eron's Pro Soccer leans Execution (Practiced Mastery); Resident Evil 6 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.

Player control and shot timing on the pitch
Resident Evil 6
Deep melee-and-gunplay movement system rewards mechanics
Keith Van Eron's Pro Soccer leans a little harder on reads, though the gap is small.

Ball physics and match randomness matter
Resident Evil 6

Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

Formation and tactic setup is learnable
Resident Evil 6
Skill builds and Mercenaries combos are learnable
