Argumentative writing is to set the format, master the fixed routine and know more facts and examples, but our teacher said that the key to writing argumentative writing is to have a good "beginning", that is, the beginning should be attractive. This is the most difficult part of argumentative writing.
It is difficult to grasp the degree to which prose must be scattered in form and spirit. If you are not careful, you will write prose narrative, not prose. You must have a profound literary foundation and cultural accumulation to use it naturally and make people feel at one go.
However, although argumentative writing is easy to write, it is not easy to write well. As long as you learn prose, you can gradually get better and get its essence. In short, argumentative writing is easier to get started than improving, while prose is just the opposite.
Of course, it does not rule out the possibility that some people are not good at a certain style. I know many people who don't write argumentative essays.
