Both are good.
Nande and Shisanxiang are both traditional Chinese condiments, each with its own unique flavor and use. Nande is a kind of chili sauce based on bean paste. It has a strong taste and is spicy, salty and fresh. It is often used in Sichuan and Hunan cuisine.
Shisanxiang is a seasoning mixed with a variety of Chinese herbs and spices. It has a rich aroma, slightly spicy and slightly sweet taste, and is suitable for cooking hot pot and other dishes. There is a clear difference in flavor between the two, making it impossible to simply decide which is better.
