Most effective formation?

[k1tb]

Which of those 4 formations could be the most effective? I know it depends also which formation is opponent using, but what do you think?
And also if you suggest one of those, maybe you could add orders also. At the moment I'm confused about which one to use as default one...

Orders maybe ? : Attacking, mixed, mixed, low, normal, man-to-man, ON counter, offside OFF.

Is playing with 3DC or 3 defenders ( DL-DC-DR ) even good ?
All the ideas and suggestions are also welcome!
