Which is better, Ding Dong or RT Mart?

Ding Dong Shopping is an O2O (online to offline) e-commerce platform. Through its own warehousing and logistics system, it directly purchases fresh ingredients from farms, and after fine processing and classification, it is sold to consumers through the Internet.

RT Mart, on the other hand, is a traditional large supermarket, which directly purchases goods from manufacturers, sorts them in a unified warehousing and logistics system, and then sells them to consumers through its own stores.
