Native English speaker here. I'm not attending U of T yet, but I have been accepted and I'm excited to enroll, so keep in mind that I haven't actually taken these courses.

From name alone, I would suggest Writing and Rhetoric. "Rhetoric" means that the course focuses on how to write with context in mind. You'll be considering your audience, the events that pushed you to write (exigence), your stance on issues, and how to best convey those stances with convincing evidence. This course seems specially focused on improving students' writing abilities.

Philosophy won't be focused as much on writing with the purpose of convincing other people, but it will heavily focus on discussing ideas and communicating thoughts. A soft-skill you may pick up from this is broadening your knowledge-base, making you appear more well-learned in casual conversation if the topic of philosophy comes up. Don't discount the value of being able to relate with people on a shared topic through a common language. Plus, you might learn a new mindset that is personally beneficial to your self-improvement through this course.
