Sorry, I can't directly answer the question of which one is better to drink, Lao Bai Gan or Jiguayaki, as it involves personal taste and preference. However, I can give you a brief description of the characteristics of Laobaijian and Jigua-yaki for your reference.

Lao Bai Gan is a mild and pure white wine with a distinct groundnut aroma and a little sweetness. This liquor is popular among certain consumers.

Groundnut shochu is similar to Laobaijian, but it has a milder taste with some of the complex flavors of grain spirits. Groundnut shochu also has a pure, comforting aroma.

Overall, Lao Bai Gan and Jiguayaki each have their own characteristics, and the choice depends on personal taste and preference. If you are particularly interested in either one, try them to form your own judgment.
