Street Fighter IVUltra Street Fighter IV
Axis by axis
Execution9 vs 9
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.

One-frame links and FADC combos demand extreme motor precision
Ultra Street Fighter IV
One-frame links and FADC timing set a brutal hands ceiling
Reads8 vs 8
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Street Fighter IV
Reading opponent habits, wake-up patterns, and adaptations is the meta
Ultra Street Fighter IV
Footsies and conditioning the human opponent is the core duel
Variance1 vs 1
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Street Fighter IV
Virtually no RNG; every outcome is skill-driven
Ultra Street Fighter IV
Almost nothing hidden once both characters are known
Optimization6 vs 6
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

Frame data, punish windows, and matchup charts are deeply studied
Ultra Street Fighter IV
Frame data, matchups and option-selects form deep studied theory
