Mahogany is generally considered better than ebony for furniture construction. While both woods are highly prized for their rich grain and durability, mahogany offers superior workability, less warping, and a wider range of finishes. Ebony, on the other hand, is denser and harder, which can make it more challenging to work with and prone to cracking.

Mahogany is a softer wood compared to ebony, which makes it easier to cut, sand, and finish. This ease of use is particularly important for furniture makers who need to shape intricate designs or create detailed carvings. Additionally, mahogany is less prone to warping and cracking, which is a significant advantage in humid environments. According to the Wood Database, mahogany has a Janka hardness rating of 2200 lbf (pounds-force), while ebony has a much higher rating of 3650 lbf. This indicates that mahogany is more forgiving for woodworking projects.

Furthermore, mahogany is more readily available and less expensive than ebony. This makes it a more practical choice for large-scale furniture production and restoration projects. Ebony, being a rarer wood, is more expensive and often reserved for high-end, custom furniture pieces.

In terms of appearance, both woods have their unique charm. Mahogany has a warm, reddish-brown color that can range from light to dark, depending on the type of mahogany. Ebony, on the other hand, is a deep black with a glossy finish that can be striking when used in contrast with lighter woods. However, the aesthetic preference often leans towards mahogany due to its versatility in color and finish options.

In conclusion, mahogany is the better choice for furniture construction due to its ease of use, durability, and cost-effectiveness. While ebony is a beautiful and durable wood, its hardness and rarity make it less suitable for most woodworking applications.
