I'm not sure about the specific difference between Michael and Nordson in grade, because the two brands are different in taste, raw materials, price and so on, so it's difficult to compare them directly. However, I can provide some information about these two brands to help you understand them better.

MCake is a French cake brand, which is widely praised for its exquisite dessert making skills and high-quality materials. However, due to the lack of relevant data, I can't evaluate its grade.

Nuoxin cake is a well-known cake brand in China, and its products are deeply loved by consumers for their delicate taste and real cheese. According to user feedback, the raw materials of Nuoxin cake are imported, which ensures food safety to some extent. In addition, Nuoxin cake is mainly ordered through the Internet, scheduled time, centralized production and distribution, and delivered directly to the door, which is convenient for consumers to buy and enjoy to some extent.

To sum up, although I can't determine the specific difference between Michael and Nuoxin in grade, Nuoxin cake has a good reputation in China, and the feedback from consumers is also good. The safety of its raw materials and the convenience of production and distribution have also been recognized by users.
