head to head
Super Smash Bros. Melee asks more than Pro Evolution Soccer 6, and the gap is execution.

Execution · Competitive PvP
The peak-era Konami football game prized for weighty, skill-driven match play.

Execution · Competitive PvP
A platform fighter with one of the highest execution ceilings in any competitive game, layered on top of deep human reads.
Pro Evolution Soccer 6 leans Execution (Competitive PvP); Super Smash Bros. Melee leans Execution (Competitive PvP).
Super Smash Bros. Melee leans clearly harder on execution.
Pro Evolution Soccer 6
First touch, through balls, and dribbles demand precise control
Super Smash Bros. Melee
Wavedashing, L-cancels, and tech-chasing set an extreme physical ceiling
Super Smash Bros. Melee leans clearly harder on reads.
Pro Evolution Soccer 6
Versus matches are constant feint and positioning prediction
Super Smash Bros. Melee
Reading DI choices and opponent adaptive habits is constant and non-convergent
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Pro Evolution Soccer 6
Deflections and keeper spills add light randomness
Super Smash Bros. Melee
Stage hazard RNG and spawn positions add marginal chaos
Super Smash Bros. Melee leans clearly harder on optimization.
Pro Evolution Soccer 6
Formations and player roles are studyable
Super Smash Bros. Melee
Character matchup tiers and optimal movement routing are deeply studied
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.
