Red Mahogany is generally considered better than Red Sandalwood due to its superior durability, workability, and aesthetic appeal. Red Mahogany is a dense, strong wood that is highly resistant to decay and insects, making it ideal for outdoor furniture and construction. It also has a rich, warm color and a fine grain that is highly sought after in woodworking. Red Sandalwood, while also prized for its color and scent, is softer and more prone to damage, limiting its applications.

Red Mahogany is a hardwood that belongs to the genus Swietenia, native to Central and South America. It is known for its high density, which ranges from 45 to 60 pounds per cubic foot. This density makes it a durable choice for furniture and construction, as it can withstand heavy use and exposure to the elements. Additionally, Red Mahogany has a Janka hardness rating of 2,200 pounds, which is significantly higher than Red Sandalwood's rating of 1,050 pounds. This higher hardness rating indicates that Red Mahogany is more resistant to dents, scratches, and wear, making it a better choice for long-lasting furniture.

In terms of workability, Red Mahogany is also superior to Red Sandalwood. It is easy to saw, plane, and nail, and it finishes beautifully, taking on a rich, warm color that darkens with age. This makes it a favorite among woodworkers for creating high-quality furniture and cabinets. Red Sandalwood, on the other hand, is softer and more difficult to work with, which can lead to more labor-intensive projects and a higher risk of damage during the manufacturing process.

Aesthetically, Red Mahogany is often preferred over Red Sandalwood. Its warm, reddish-brown color is highly sought after in furniture design, and its fine grain pattern adds visual interest. Red Sandalwood, while also having a beautiful color, is less consistent in grain and can sometimes have a more subdued appearance. Furthermore, the scent of Red Sandalwood is often associated with luxury and exoticism, but this scent can be overpowering in certain applications, whereas the scent of Red Mahogany is less intense and more subtle.

In conclusion, Red Mahogany is the better choice between the two due to its superior durability, workability, and aesthetic appeal. According to the Janka hardness test, Red Mahogany is significantly harder than Red Sandalwood, making it more resistant to damage. Additionally, Red Mahogany is easier to work with and has a more consistent and appealing color and grain pattern. These factors make Red Mahogany the preferred option for many woodworkers and furniture designers.
