Best practice for multiple sections

In the previous courses I've taught using, I've only had one section (i.e. one cohort of students) at a time, so creating a single space made sense.

I am about to embark on teaching a new course, which has multiple sections. I am leaning to creating a separate space for each section, but I can see pros and cons on both sides...a single space would mean not having to duplicate uploads, for example.

Does anyone have any wisdom to offer on this?
