head to head
Super Smash Bros. Melee asks more than Dragon Ball Z: Battle of Z, and the gap is execution.

Execution · Competitive PvP
A team arena brawler testing loose execution and squad composition over precision.

A platform fighter with one of the highest execution ceilings in any competitive game, layered on top of deep human reads.
Dragon Ball Z: Battle of Z leans Execution (Competitive PvP); Super Smash Bros. Melee leans Execution (Competitive PvP).
Super Smash Bros. Melee leans clearly harder on execution.

Aerial chases and ki timing need moderate hands
Super Smash Bros. Melee
Wavedashing, L-cancels, and tech-chasing set an extreme physical ceiling
Super Smash Bros. Melee leans clearly harder on reads.
Dragon Ball Z: Battle of Z
Team fights against humans involve loose target prediction
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.
Dragon Ball Z: Battle of Z
Little hidden beyond card drops for builds
Super Smash Bros. Melee

Super Smash Bros. Melee leans clearly harder on optimization.
Dragon Ball Z: Battle of Z
Team synergy cards and role composition are the system layer
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.
