Flags of Our Fathers or Letters From Iwo Jima?

I recently watched both of them, and boy, they’re both fantastic movies. I started out watching Flags of Our Fathers, thinking that it would be the better of the two. Boy, was I ever so wrong. Letters From Iwo Jima is a much, much, better movie in every aspect, not that Flags of Our Father is a bad movie by any means.

So, which one do you prefer?
