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
Analog-stick boxing testing punch precision and counter-baiting against human opponents.

Execution · Competitive PvP
The peak-era Konami football game prized for weighty, skill-driven match play.
Fight Night 2004 leans Execution (Competitive PvP); Pro Evolution Soccer 6 leans Execution (Competitive PvP).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Fight Night 2004
Analog punch control and block timing are the core test
Pro Evolution Soccer 6
First touch, through balls, and dribbles demand precise control
Pro Evolution Soccer 6 leans a little harder on reads, though the gap is small.
Fight Night 2004
Versus humans, baiting counters and feinting is genuine prediction
Pro Evolution Soccer 6
Versus matches are constant feint and positioning prediction
Pro Evolution Soccer 6 leans a little harder on variance, though the gap is small.
Fight Night 2004
Outcomes follow inputs with little randomness
Pro Evolution Soccer 6
Deflections and keeper spills add light randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Fight Night 2004
Stat training and stamina management add a planning layer
Pro Evolution Soccer 6
Formations and player roles are studyable
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.
