Also, LE version is limited to 25mb containers (while TrueCrypt have none).

Even if the PE (professional edition, non-free) have 448bit encryption and higher size limitations, I'm uncertain how this would compare to a 256bit*3 encryption.

Also TrueCrypt also have additional features such as a hidden container in the container.
