After reading about these papers here, I decided to try some out.
1. Exacompta ruled journal: this actually has a surprisingly rough texture and is off-white. I'm not sure I like it, as the color of blue ink doesn't really show up as well as with white paper. And there is actually the occasional slub in the paper that the nib can catch on. However, the paper does not feather or bleed at all, which is good. Although I've learned here that Exacompta is under the same umbrella as Clairefontaine, the paper in this journal is very different. Also, the lines are spaced quite wide apart, meaning you need a medium or broad nib and can fit less writing on a page. There are probably people who like all these features, but I'm not sure I'm one of them.
2. Clairefontaine ruled pads: silky smooth, ultrawhite, and no bleeding or feathering at all. Wow! i see why people rave about this paper. For me, another nice feature is that the pads I got from Swisher's are actually exactly the same size as the paper in the medium-sized Levenger circa notebooks, and I have a punch that will allow me to bind the Clairefontaine paper in these notebooks.
3. I picked up a pocket-sized Moleskine ruled notebook in a local stationery store. The paper is a disappointment, however. Very thin, and almost all of my inks bleed through to the other side of the page. The notable exception is Aurora Blue, which makes absolutely zero bleedthrough. The sensation of writing on this paper is actually very interesting. The only way I can describe it is that it feels like the paper is melting under the nib.
Still, I found it very handy to carry one of these on my recent trip, to store important little bits of information.
I have read elsewhere that there may be some variation in the paper quality in different Moleskines. Does anyone know if the larger ones have better paper?
