Lantly, your description of what an x-chock and other chocks will do is correct. But, the OP's original post asked which would stop rocking. As I said, neither stops rocking. Both help to eliminate wheel movement, but rocking still occurs at the axles, springs and shackles. Unless one has 4 or 6-pt leveling, movement will occur.
I used the word rocking to describe the back and forth movement of the wheels/tires as people move inside. The X-Chocks and ONEstep both work to stop the rotation of the tires, drastically reducing the feeling of movement inside the camper.
Its still a camper, I'm not trying to eliminate all movement... just reduce it enough to prevent us waking up the kids or the kids waking us up. I'm very satisfied with the result. The ONEstep happens to also serve as a chock and doesn't require adjustment after the tires cool.
