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

Execution · Grand Arena
A 2D fighting game where execution meets relentless yomi at neutral.

Execution · Competitive PvP
A platform fighter with one of the highest execution ceilings in any competitive game, layered on top of deep human reads.
Street Fighter 6 leans Execution (Grand Arena); Super Smash Bros. Melee leans Execution (Competitive PvP).
Super Smash Bros. Melee leans a little harder on execution, though the gap is small.
Street Fighter 6
Frame-perfect inputs and combos are mandatory.
Super Smash Bros. Melee
Wavedashing, L-cancels, and tech-chasing set an extreme physical ceiling
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Street Fighter 6
Adaptive opponent baits Drive Impacts and throws.
Super Smash Bros. Melee
Reading DI choices and opponent adaptive habits is constant and non-convergent
Super Smash Bros. Melee leans a little harder on variance, though the gap is small.
Street Fighter 6
Essentially no randomness in match outcomes.
Super Smash Bros. Melee
Stage hazard RNG and spawn positions add marginal chaos
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Street Fighter 6
Matchup charts, frame data, and combo routes.
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.
