dvj cant do perfect electrics only kazuya can.
fastest normal electric possible is 14 frames and perform-able by all mishimas but kazuya can do f,d,df or f,n,df to do a 13 frame perfect electric

devil jin has a few good panic moves that evade anything and has great pressure tools but has a decently high execution requirement

akuma is stupid powerful but has a very high execution requirement

steve is just mashing buttons and winning, as far as i can tell 0 execution requirement. you just need slimeball hands to smash against the punch and kick buttons
