Pear wood is generally considered better than elm wood for several reasons. While both woods have their unique characteristics, pear wood tends to be more versatile, durable, and aesthetically pleasing.

Pear wood is known for its fine grain and smooth texture, which makes it ideal for furniture making and joinery. It is also highly durable, with a Janka hardness rating of around 1,200, which is comparable to oak. This durability ensures that furniture made from pear wood will last for many years without significant wear. Additionally, pear wood has a pleasant aroma and a warm, rich color that enhances the visual appeal of furniture pieces.

In contrast, elm wood is also durable but has a coarser grain and a less refined texture. It is often used for outdoor furniture and construction due to its strength and resistance to decay. However, elm wood can be prone to warping and cracking over time, which may affect its long-term stability. Elm wood has a Janka hardness rating of around 1,200 to 1,300, similar to pear wood, but its lower quality and less refined appearance make it less desirable for high-end furniture and woodworking projects.

According to the Wood Database, pear wood has a higher bending strength and stiffness than elm wood, which makes it more suitable for structural applications. The bending strength of pear wood is approximately 12,000 psi, while elm wood's bending strength is around 11,000 psi. This slight difference in mechanical properties can be significant when considering the intended use of the wood.

Furthermore, pear wood is more resistant to moisture and decay than elm wood, making it a better choice for environments where exposure to water is a concern. Elm wood is more susceptible to fungal growth and can be affected by moisture, which can lead to structural issues over time.

In conclusion, pear wood is generally considered better than elm wood due to its superior durability, aesthetic appeal, and mechanical properties. While elm wood has its uses, particularly in outdoor applications, pear wood offers a more versatile and long-lasting option for furniture and woodworking projects.
