Which is better, Little Sheep Clear Soup or Haidilao Clear Soup, depends on personal taste and preference. However, the following reference information can be provided:

1. The clear soup base of Haidilao has a strong mutton flavor and is a little salty, which is suitable for people who like soup, want to eat light food and don't like spicy food. The bottom of the clear soup pot in Haidilao is also delicious for cooking noodles.

2. The bottom of Little Sheep's pot tastes just right, and it won't get more and more salty. In terms of service, Haidilao is better and the service is super meticulous, but sometimes it makes people feel a little tired.

In short, both of them have their own advantages and disadvantages. I suggest you choose according to your own tastes and preferences.
