head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Competitive PvP
Striking execution and constant human mix-up prediction across MMA phases.

Execution · Competitive PvP
The Wii U Smash that restored competitive pace and a huge roster of labbable kill confirms.
EA Sports UFC 5 leans Execution (Competitive PvP); Super Smash Bros. for Wii U 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.
EA Sports UFC 5
Strike timing, head movement and transition denial demand hands
Super Smash Bros. for Wii U
Perfect pivots and precise aerial spacing reward sharp hands.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
EA Sports UFC 5
Out-guessing a human's strike-grapple mix is the core duel
Super Smash Bros. for Wii U
Ledge-trap and landing-trap guessing against humans never converges.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
EA Sports UFC 5
Damage events and doctor stoppages add chaos
Super Smash Bros. for Wii U
Tripping removed; only minor move RNG remains.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
EA Sports UFC 5

Super Smash Bros. for Wii U
Rage mechanics and kill-confirm percents are deeply labbable.
