Street Fighter IVX-Men vs. Street Fighter
Axis by axis

Infinite combos and tag execution demand serious hands.

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
X-Men vs. Street Fighter
Human opponents adapt mixups every round.
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
X-Men vs. Street Fighter
Fully visible game state.
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
X-Men vs. Street Fighter
Team synergy and matchup theory reward lab time.
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.
