The poll results here are pretty similar to Cottonelle's results. I remember seeing billboards all over LA for their ad campaign before the summer.
I prefer over as well.
On January 27, 2010, the one hundredth anniversary of Thomas Crapper's death,[23] Cottonelle launched a "Great Debate" advertising campaign, inviting American consumers to vote their preference at a Kimberly-Clark website.[57] The result was announced during the 82nd Academy Awards: 72% had voted over.[58] In a more traditional preliminary survey of 1000 Americans, Cottonelle found that "overs" are more likely than "unders" to notice a roll's direction (74%), to be annoyed when the direction is incorrect (24%), and to have flipped the direction at a friend's home (27%).[59]
