I choose Taobao because it was established earlier and is the pioneer in the e-commerce industry. Later Pinduoduo, JD.com, and Shopee basically imitated Taobao. Douyin is essentially a short video platform. Although it has added e-commerce functions and started selling goods, I personally think that Douyin operation is more difficult than Taobao because it requires strong content creation capabilities, such as copywriting, scripts, shooting, conception, editing, traffic diversion, customer operation, live broadcast operation, data analysis, etc.
