In terms of overall quality and characteristics, ebony is generally considered better than rosewood. Ebony is known for its exceptional hardness, durability, and rich, dark color, making it highly sought after for high-end musical instruments and furniture. Rosewood, while also a premium wood, may not match ebony in terms of these specific attributes.

The hardness of wood is a crucial factor in its suitability for certain applications. Ebony has a Janka hardness rating of around 2,200, which is significantly higher than rosewood's rating of about 1,450. This means that ebony is more resistant to wear and tear, making it ideal for instruments that require long-lasting quality and durability. The higher hardness also contributes to the wood's ability to produce a rich, deep tone in musical instruments.

In terms of color, ebony's deep, dark hue is often preferred for its aesthetic appeal. While rosewood also offers a rich color, it tends to have a more reddish tint, which may not be as universally appealing. The dark color of ebony also makes it less susceptible to fading over time, maintaining its appearance for longer periods.

Data from the Wood Database supports these claims. The Janka hardness rating for ebony is consistently higher than that of rosewood, indicating its superior durability. Additionally, studies have shown that the dark color of ebony is more resistant to fading compared to the reddish hue of rosewood. These factors contribute to the perception that ebony is a better choice overall.
