La Notte, L' Elisse or L' Avventura? Which one is better?

So I purchased La Notte on amazon.com before I ever watched it. I saw that it was very well spoken about by critics on The Documentary film Z Channel (which I recommend to anyone, especially if you're into older films) so it interested me and I bought it.

It took me the second time I saw it to really appreciate it. It was slow moving and wasn't packed with excitement but It was a great film.

Im planning on buying more films by the director of La Notte so to get to the point. Which one of the three (La Notte, L' Elisse, L' Avventura)is better?

By the way, if there is a movie that he has done that is not on the three I pointed out let me know also. But if you seen the three I mentioned let me know which one you preferred.

Thanks
