head to head
Neither is simply harder - they are hard in different places. EA Sports FC 26 demands more variance; Super Smash Bros. Melee demands more execution.

Execution · Competitive PvP
Stick-skill football where outguessing human opponents matters as much as mechanics.

Execution · Competitive PvP
A platform fighter with one of the highest execution ceilings in any competitive game, layered on top of deep human reads.
EA Sports FC 26 leans Execution (Competitive PvP); Super Smash Bros. Melee leans Execution (Competitive PvP).
Super Smash Bros. Melee leans clearly harder on execution.
EA Sports FC 26
Dribbling, skill moves and finishing need precise stick work
Super Smash Bros. Melee
Wavedashing, L-cancels, and tech-chasing set an extreme physical ceiling
Super Smash Bros. Melee leans clearly harder on reads.
EA Sports FC 26
Online matches hinge on baiting and predicting human defenders
Super Smash Bros. Melee
Reading DI choices and opponent adaptive habits is constant and non-convergent
EA Sports FC 26 leans clearly harder on variance.
EA Sports FC 26
Deflections, ref calls and Ultimate Team packs add randomness
Super Smash Bros. Melee
Stage hazard RNG and spawn positions add marginal chaos
Super Smash Bros. Melee leans a little harder on optimization, though the gap is small.
EA Sports FC 26
Squad building, tactics and meta mechanics reward study
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.
