Judging from the quality of disciplines, politics and law are more comprehensive and teachers are stronger. If you want to listen to every class, you can take classes every day. This is the advantage of politics and law. The lectures and other resources of politics and law are all around the law, and the legal atmosphere is stronger. The advantage of the National People's Congress (NPC) is that the two main branches of law, civil law and criminal law, are very powerful. After all, it is a national key discipline of NPC.
From the employment point of view, NPC undergraduate law degree is generally better than political science and law, but the key is not the law firm, NPC graduates are more civil servants. Although politics and law also belong to the category of civil servant training base, relatively speaking, the proportion of going to law firms is higher than NPC. It is not easy for undergraduates to be lawyers. No matter your major is politics and law, it is difficult to go to a first-class law firm unless your foreign language is particularly good. At this stage, graduate students are more about the first-class law firms such as Hejun, Jindu and Shanghai.
From the perspective of contacts, politics and law are undoubtedly richer. The number of procuratorates, courts and universities of political science and law in Beijing is greater than or equal to the sum of NPC, Peking University and Tsinghua, not to mention the lawyer circle, which covers almost every law firm. This is mainly based on the fact that there are many more people studying law in politics and law than in other schools.
To sum up, there is no absolute good or bad, the key is which factor you attach more importance to.
