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 · Competitive PvP
The N64 original that turned Nintendo mascots into a percent-and-knockback platform fighter.

Execution · Competitive PvP
A precision tennis game testing swing timing and reading human opponent court patterns.
Super Smash Bros. leans Execution (Competitive PvP); TopSpin 2K25 leans Execution (Competitive PvP).
TopSpin 2K25 leans a little harder on execution, though the gap is small.
Super Smash Bros.
Z-cancels and DI demand fast precise inputs despite simple controls.
TopSpin 2K25
Swing timing windows and footwork positioning require precision
Super Smash Bros. leans a little harder on reads, though the gap is small.
Super Smash Bros.
Edgeguard and tech-chase guessing against adapting humans decides stocks.
TopSpin 2K25
Reading human opponent's shot patterns and court positioning matters
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Super Smash Bros.
Item spawns add randomness; tournament rules strip most of it.
TopSpin 2K25
Minimal RNG; outcomes reflect skill cleanly
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Super Smash Bros.
Stage positioning and percent-based kill setups are learnable.
TopSpin 2K25
Playstyle builds and shot selection form a learnable system
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.
