Because poetry and prose are very difficult (writing poetry is not allowed in some places), narrative is a little shallow compared with argumentative writing, and the college entrance examination emphasizes students' speculation, so argumentative writing has become the mainstream choice ... but argumentative writing is not so easy to write, and it often digress, even if it doesn't digress, the theme is not deep enough and it is difficult to attract attention.

All in all,

Argumentative essay-as long as you don't stray from the topic, the score will not be very low, but it will not be very high. It's hard to get high marks.

Narrative-even if you don't stray from the topic, your score will generally be lower than that of argumentative writing (except for narrative and discussion), but the difficulty of high score is lower than that of argumentative writing.

Prose is more difficult to write than argumentative writing, so the upper limit of score is higher than argumentative writing, and the lower limit is lower than argumentative writing.

Weigh it according to your writing style and the exam.

This is my personal opinion, I hope it will help you ~
