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

Execution · Competitive PvP
The Deadly Alliance follow-up adding combo breakers, death traps, and online play.

Execution · Competitive PvP
The N64 original that turned Nintendo mascots into a percent-and-knockback platform fighter.
Mortal Kombat: Deception leans Execution (Competitive PvP); Super Smash Bros. leans Execution (Competitive PvP).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Mortal Kombat: Deception
Style strings plus stage-hazard spacing demand control
Super Smash Bros.
Z-cancels and DI demand fast precise inputs despite simple controls.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mortal Kombat: Deception
Human opponents bait death traps and breakers
Super Smash Bros.
Edgeguard and tech-chase guessing against adapting humans decides stocks.
Super Smash Bros. leans a little harder on variance, though the gap is small.
Mortal Kombat: Deception
Deterministic outside known stage hazards
Super Smash Bros.
Item spawns add randomness; tournament rules strip most of it.
Mortal Kombat: Deception leans a little harder on optimization, though the gap is small.
Mortal Kombat: Deception
Combo routes and hazard positioning are lab work
Super Smash Bros.
Stage positioning and percent-based kill setups are learnable.
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.
