I have a few inserts, like The Postman Always Rings Twice, War of the Worlds, Psycho and about 100 others, but yeah, not into the format much. 1/2 sheet, very few also. Best titles are Laura, The Prince and the Showgirl and a few others, but it's really on a per title basis.
You're right, I like BIG posters, French, Italians are the best imo. I only buy posters of movies I've seen (essential to me) and will always focus on international before US, because the art is SO much better.
