It'll mostly depend on your players. There are a couple of alternative 4-3-3 ideas you can implement.
Wide winger style: the two outer forwards will be playing as wingforwards: pacy, hugging the touchline and always taking on their man. Putting in crosses from the byline or dribbling inwards. This will need a centre forward who can head the crosses in. Also, one or two of the midfielders will need to make (late) forward runs to support the striker and be on the receiving end of the crosses or through balls. If you want to use attacking fullbacks with this, you'd need to put one of the midfield players in the DMC position.
Screening midfield: you put three hard working and tackling midfielders in the middle of the park (eg Essien). These three form a 'screen' in front of your defense, while all three of your forwards a fast strikers who'll run in space. This can be quite a nice system when used with overlapping fullbacks. This is a system that should be played deeper in your own half (using counter attacks) and can be player more narrow than the first one.
Deep striker: the striker in the center comes deep to receive the ball (to AMC position). This is a variant I personally don't like to play, but can be needed when you lack a quality finisher.
Of course, keep in mind that there are many variations possible within these ideas. The most important thing to remember is that your tactic needs to be based on both your own players and your opponent's.
