The paper is NOT the same as Rhodia. It's much smoother and noticeably heavier. While Exacompta owns both Clairefontaine and Rhodia now, they used to be different companies entirely, and the different brands are still made in their original separate factories [EDIT: not the same factories, but the same machines] and retain their own character. The exception is Rhodia's "R" premium line, which was launched after Exacompta acquired the brand. That line, and that line only, is the same paper as ivory-colored Clairefontaine paper. Both brands have great paper, so it comes down to personal preference. I personally find Rhodia an excellent paper, and I love it and use it all the time, but it's not luxurious to write on the way Clairefontaine paper is.
