Wenge is generally considered better than walnut wood due to its unique grain pattern, durability, and hardness. Wenge has a distinctive black and gold striped grain that adds visual appeal to furniture and flooring. It is also harder and more durable than walnut, making it suitable for high-traffic areas. Walnut, while also a durable and attractive wood, lacks the distinctive grain pattern and is not as hard as wenge.

Wenge is a dense, heavy wood with a Janka hardness rating of 2,320 lbf (pounds-force), which is significantly higher than walnut's rating of 1,290 lbf. This hardness makes wenge less prone to dents and scratches, making it a better choice for furniture that will be used frequently. Additionally, wenge has a higher resistance to moisture, which is important for areas with high humidity or exposure to water. Walnut, while still durable, is not as moisture-resistant as wenge.

In terms of appearance, wenge's striking grain pattern is often preferred for its elegance and uniqueness. The alternating black and gold stripes create a sophisticated look that can elevate the design of any piece of furniture or flooring. Walnut, on the other hand, has a rich, warm brown color with a straight grain that can be less visually striking compared to wenge.

According to the Wood Database, wenge is also known for its stability, which means it does not expand or contract significantly with changes in humidity. This stability is crucial for maintaining the integrity of furniture over time. Walnut, while stable, may experience slight changes in size and shape due to humidity fluctuations.

In conclusion, wenge is generally considered better than walnut wood due to its superior hardness, durability, moisture resistance, and distinctive grain pattern. These factors make it a more suitable choice for high-quality furniture and flooring that require both aesthetic appeal and long-lasting performance.
