Which is better, walnut or ash?

Two are varieties of different grades. Walnut is a high-end rare wood with limited use. Fraxinus mandshurica is an ordinary large and medium-sized wood. Walnut is hard, not easy to deform, and of good quality, which will last for a long time. Fraxinus mandshurica has good elasticity, can create the style people want, has good moisture-proof effect and is affordable.
