Magda, they are very similar when you want to say:

You must see this move - You have to see this movie.

He must be home by 10 p.m. - H has to be home by 10 p.m.

I must leave now - I have to go now.

More options:

• If you are eager to do something but see or foresee some obstacles, you say: 'I have got to/gotta do it' ('I always knew I had got to do it' [Tina Turner

Because "I must do it" is a subjective statement.
