Zitan is generally considered better than Wenge for several reasons. Zitan, also known as Chinese rosewood, is prized for its rich red color, exceptional durability, and unique grain patterns. It is a member of the Dalbergia genus, which includes other high-quality woods like Rosewood and African Blackwood. Wenge, on the other hand, is a dense and heavy wood with a distinctive black and brown striped pattern, but it lacks the same level of durability and aesthetic appeal as Zitan.

One of the primary reasons Zitan is preferred over Wenge is its hardness and resistance to wear. Zitan has a Janka hardness rating of around 2,820 lbf (12,580 N), which is significantly higher than Wenge's rating of about 2,580 lbf (11,470 N). This means Zitan is more resistant to scratches, dents, and general wear and tear, making it a superior choice for furniture and other high-quality woodworking projects.

Additionally, Zitan's rich red color and distinctive grain patterns offer a unique aesthetic appeal that is highly sought after in fine woodworking. The wood's color can range from a deep red to a rich mahogany, and its grain patterns can vary from straight to highly figured, with a variety of swirls and patterns. This versatility in color and grain makes Zitan a favorite among woodworkers and furniture designers.

In terms of sustainability, Zitan is also a more responsible choice. While Wenge is listed as a critically endangered species on the CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) Appendix II, Zitan is not as heavily regulated. This means that Zitan is more readily available and less likely to contribute to the depletion of endangered species.

Data from the Janka hardness test and the CITES listing provide clear evidence that Zitan is a superior choice to Wenge. The higher hardness rating of Zitan ensures greater durability and longevity, while the less stringent regulations surrounding Zitan make it a more sustainable option for woodworkers and consumers alike.
