Baoning vinegar and Zhenjiang vinegar have their own advantages, but it is impossible to directly judge which is better. We can compare them from the following aspects:

1. Features: Baoning vinegar is made of more than 60 kinds of traditional Chinese medicines and brewed with winter water from Jialing River. It is rich in fragrance and slightly sweet in sour taste, and has the effects of promoting fluid production to quench thirst, stimulating appetite, strengthening the spleen and invigorating the spirit. Zhenjiang vinegar uses glutinous rice, malt, etc. As raw materials. After brewing, it has a unique aroma and sour taste, and its color is bright.

2. Nutrition: Baoning vinegar is rich in amino acids, calcium, phosphorus, iron and other nutrients, which helps to promote blood circulation and digestion. Zhenjiang balsamic vinegar contains a variety of vitamins and minerals, which helps to improve immunity.

3. Acidity: Baoning vinegar has high acidity and is suitable for seasoning. Zhenjiang balsamic vinegar has low acidity and is suitable for cooking and seasoning.

To sum up, we can't directly judge which vinegar is better, because both of them have their own advantages in characteristics, nutrients and acidity. The choice of vinegar mainly depends on personal taste and use.
