Wait, or polled wait?

For cinematics, should I be using a wait, or a polled wait (game time wait).


For regular things like panning cameras and creating units, should I use a wait or polled wait?

Thanks much.

it does not matter,
a "wait" will make the trigger wait before he do the rest of its actions, a "wait Game time" will just make a wait but the trigger will still run.

elaborate plz.
