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

Fast arena combat that tests combo execution and counter prediction against human opponents.

Execution · Competitive PvP
The peak-era Konami football game prized for weighty, skill-driven match play.
Dragon Ball Z: Budokai Tenkaichi 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.
Dragon Ball Z: Budokai Tenkaichi
Combo timing, dashes and beam clashes reward fast hands
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.
Dragon Ball Z: Budokai Tenkaichi
Versus humans, predicting teleport counters and ki tactics matters
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.
Dragon Ball Z: Budokai Tenkaichi
Almost nothing random once movesets are known
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.
Dragon Ball Z: Budokai Tenkaichi
Character matchups and attribute builds are learnable systems
Pro Evolution Soccer 6
Formations and player roles are studyable
