Axis by axis
Execution6 vs 7
Street Fighter leans harder on execution: Notoriously stiff inputs make landing specials the real fight

Variance0 vs 1
Street Fighter leans harder on variance: Nothing hidden between two visible fighters
Optimization1 vs 2
Street Fighter leans harder on optimization: Tiny moveset leaves little system to solve
