head to head
Super Smash Bros. Melee asks more than WWE 2K Battlegrounds, and the gap is reads.

Execution · Competitive PvP
A platform fighter with one of the highest execution ceilings in any competitive game, layered on top of deep human reads.

Execution · Competitive PvP
Arcade wrestling that tests reversal timing and little else by design.
Super Smash Bros. Melee leans Execution (Competitive PvP); WWE 2K Battlegrounds leans Execution (Competitive PvP).
Super Smash Bros. Melee leans clearly harder on execution.
Super Smash Bros. Melee
Wavedashing, L-cancels, and tech-chasing set an extreme physical ceiling
WWE 2K Battlegrounds
Button-mash combos and reversal timing set the pace
Super Smash Bros. Melee leans clearly harder on reads.
Super Smash Bros. Melee
Reading DI choices and opponent adaptive habits is constant and non-convergent
WWE 2K Battlegrounds

Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Super Smash Bros. Melee
Stage hazard RNG and spawn positions add marginal chaos
WWE 2K Battlegrounds
Power-ups and interactive arenas inject party chaos
Super Smash Bros. Melee leans clearly harder on optimization.
Super Smash Bros. Melee
Character matchup tiers and optimal movement routing are deeply studied
WWE 2K Battlegrounds
Shallow systems - move knowledge helps a little
