I've been using Cuados s.a.s notebooks for a while now, and I have to say they are fantastic. The paper quality is excellent, and the binding is sturdy. I also appreciate the attention to detail in the design. The variety of sizes and formats available is a big plus. The only downside is that they are a bit pricey compared to other brands, but in my opinion, the quality justifies the cost.
