In the realm of auspicious woods for warding off evil, ebony is generally considered more auspicious than peach wood. This belief is rooted in various cultural and historical practices, particularly in Eastern cultures where the properties of different woods are often associated with spiritual and protective qualities.

Ebony, known for its dark, dense, and heavy grain, has been revered for centuries for its supposed protective properties. In many Eastern cultures, ebony is believed to possess strong spiritual energy that can repel negative influences and attract good fortune. This belief is supported by traditional Chinese medicine, which attributes certain healing properties to ebony, including its ability to balance the body's energy and protect against evil spirits.

On the other hand, peach wood, while also valued for its beauty and durability, is not typically associated with the same level of auspiciousness as ebony. Peach wood is often used in furniture and crafts due to its pleasant aroma and workability, but it lacks the same historical and cultural significance when it comes to warding off evil.

One reason for the preference of ebony over peach wood is the historical use of ebony in protective amulets and talismans. For example, in Japan, ebony is used in the creation of okimono, which are small wooden objects believed to bring good luck and protect against evil. The dark color and dense grain of ebony are thought to enhance its protective properties.

Furthermore, scientific research has provided some insight into the properties of ebony that may contribute to its auspiciousness. Studies have shown that certain woods, including ebony, contain natural oils and resins that can have antimicrobial and antiviral properties. While this does not directly relate to warding off evil in a spiritual sense, it does suggest that the physical properties of ebony may contribute to its protective qualities.

In conclusion, ebony is considered more auspicious for warding off evil compared to peach wood, primarily due to its historical and cultural significance in protective practices and its physical properties that may contribute to its protective qualities.
