The Hardcover Lamy Notebook is sharp looking, and feels great while writing in it. I really like using it because of its unique paper design - having both a dotted grid and alternating full lines at the same time.
The paper is good and able to stand up to very wet fountain pen strokes. I tested it with medium and fine nibs using Lamy Safari and Al-Star pens with varying inks. The result was good. Although the paper is not as smooth and resistant to wet ink as my Rhodia Rhodiarama Notebook; the pen strokes still came out flawlessly and elegantly. There was no feathering, and the backside of the pages never had bleed-through of the ink. But if I had to choose, I would still say that the paper in my Rhodia notebook is superior. Writing on the Rhodia paper is simply smoother feeling, and strokes are also slightly slimmer.
The Notebook I bought was the Hardcover Lamy Notebook in A5 size with Silver cover and purple accented pages. I really like the hybrid dot grid pattern with the alternating horizontal lines. This gives the paper a design not seen in other notebooks. I sometimes have skewed writing while using my Rhodia notebook, and the alternating lines in the Lamy are a great way to keep my writing straight. When spread-out the notebook remains reasonably flat despite being hardcover. The Lamy also has two bookmarks, an internal pocket, an elastic closing band, and an elastic pen loop. The pen loop itself is somewhat tight -and getting a Lamy Safari pen to sit inside of it requires some careful effort. (Thinner pens and normal pencils will easily fit though.) Also, the notebook has some sharp corners in its hardcover form - whereas the softcover version has rounded corners.
While not perfect, the Lamy A5 Hardcover notebook is still a pleasure to use. I would still choose a Rhodia notebook's paper for purely fountain pen use, but the Lamy still gets my vote for general use simply because of that unique dot grid and line pattern printed on each page. The paper stands up to any common pen, fountain pen, or pencil that most people would use to take notes with.
