FSM Declaration with Strings vs enmubs

WithEnumbs.as

// state names
public static const LOADING:StateName = new StateName("loading");
public static const DECODING:StateName = new StateName("decoding");
public static const DISPLAYING:StateName = new StateName ("displaying");

// process names
public static const IN:ProcessName = new ProcessName("in");

// state declaration
fsmConfig.configureState( LOADING )
     .withTransitionTargets( DECODING );

fsmConfig.configureState( DECODING )
     .withTransitionTargets( DISPLAYING );

fsmConfig.configureState( DISPLAYING )
     .withTransitionTargets( LOADING );

// process declaration
fsmConfig.configureProcess( IN )
     .ifCurrentState( DISPLAYING )
     .transitionTo( LOADING, DECODING, DISPLAYING );

WithStrings.as

// state names
public static const LOADING:String = "state/loading";
public static const DECODING:String = "state/decoding";
public static const = "state/displaying";

// process names
public static const IN= "process/in";

// state declaration
