Building comparison
head to head
Killer Instinct (2013)vsSuper Smash Bros. Melee
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

A combo system built on constant Combo Breaker mind-games that create a unique adaptive read-off at every moment of a combo.
Super Smash Bros. Melee
Execution · Competitive PvP
A platform fighter with one of the highest execution ceilings in any competitive game, layered on top of deep human reads.

Axis by axis
Execution9 vs 10

Killer Instinct (2013)
Combo Breaker prediction is a pure read-off against an adaptive opponent
Super Smash Bros. Melee
Reading DI choices and opponent adaptive habits is constant and non-convergent

Killer Instinct (2013)
No RNG; all mechanics are fully visible
Super Smash Bros. Melee
Stage hazard RNG and spawn positions add marginal chaos

Killer Instinct (2013)
Instinct activation timing and optimal opener routes are well-studied
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.
