This is often a topic of discussion among English majors. Which one is better? The answer is simple: It all depends on what you want to do after graduation. If you want to be an author, poet, novelist, etc. the creative writing courses are going to be a better fit. If you want to write technical documents such as grant proposals, research proposals, manuals, procedural documents, etc. the technical writing classes will be good courses to take.
Many English majors choose to take technical writing classes, but they also write creatively on the side. A friend told me that every English major secretly works on writing a book, a poem, or a play, etc. I think he was right. By nature, we love to write and tell stories.
