both are good i prefer sf style though.
the main problem are the goddamn "shortcuts"
i hate them because they destroy your execution.
the developters put them in so the noobs can pull off combos and dps, easier!
best examples:
(sf4) dragon punch: without shortcut f, d, df, punch - shortcut: df,df punch
(mk9) special: without shortcut d, f, button - shortcut: df, button.
i wish the damn shortcuts could be DISABLED, that would be an NICE feature!
