Some people like workspaces because you can have one for every type of activity to keep them separate. This is a bit like minimizing as it gets rid of what you had on the screen without closing it. You can get really fast at switching apps after you get used to it. Then you simply click which workspace you want (or a new one). Clicking “Activities” in the top-left corner or pressing the windows button brings up app shortcuts on the left and workspaces on the right side of the screen.
As far as I can tell Pop!_OS users are supposed to utilize the ancient Linux “workspaces” feature.
