Sandalwood is generally considered better than pepperwood due to its superior scent, durability, and cultural significance. Sandalwood oil, derived from the heartwood of the sandalwood tree, is highly valued for its aromatic properties and has been used in perfumery, incense, and traditional medicine for centuries. Pepperwood, on the other hand, has a more pungent and less refined scent, and its uses are more limited compared to sandalwood.

The scent of sandalwood is often described as warm, sweet, and rich, with a subtle, lingering quality that makes it highly sought after in the fragrance industry. Sandalwood oil has a high concentration of santalol, a compound that contributes to its distinctive aroma and is known for its calming and soothing effects. In contrast, pepperwood has a more sharp and pungent scent, which is less versatile in applications requiring a refined or delicate fragrance.

In terms of durability, sandalwood is also superior. It is one of the hardest woods in the world, making it highly resistant to decay and insects. This durability makes sandalwood ideal for use in furniture, carving, and construction, where it can last for generations. Pepperwood, while also durable, is not as hard as sandalwood and is more commonly used for less demanding applications.

Culturally, sandalwood holds significant importance in many societies. It has been used in religious ceremonies, meditation, and as a symbol of purity and tranquility. The wood itself is often associated with luxury and elegance, and sandalwood oil is considered a precious commodity. Pepperwood, while also used in traditional practices, does not carry the same level of cultural significance or value.

Data supporting these claims can be found in various studies and publications. For instance, a study published in the Journal of Essential Oil Research in 2012 analyzed the chemical composition of sandalwood oil and found that it contains high levels of santalol, which contributes to its unique scent and therapeutic properties. Additionally, the book "Wood: A Dictionary of Timbers" by John Hill and John Beardsley notes the exceptional hardness and durability of sandalwood, making it a superior choice for long-lasting applications.
