The Detail Tool and the Worksheet Tool create working windows that are essentially identical in function. How you choose to use them is entirely up to you.
And until you create Views with one or the other tool, you aren't really creating anything that you can put onto a sheet (layout).
One way to make sense of the two is to use the Detail Tool to create snapshots from the live model, and to use Worksheets to house external information like the DWGs or PDFs, or images, imported from outside the BIM.
In this context, the information created in a View from a Detail derives from what you have modeled. This needs to be kept in mind as you work. Live model Views can be information rich, well articulated up to a scale of 1:100, 1:50, or even 1:25. You have to decide what the threshold between live and drawn is. Something modeled with 1:100 in mind would probably have fewer modeled elements and more drawn elements in details than a project where the threshold is set at 1:50.
Keeping the two separated allows you to edit or adapt an outside detail to the specifics of your project. Once that's done, you could transfer this linework and annotation to a single layer, copy and paste it into the View you created from the Detail. From that point, the information consists of content from the outside AND the BIM itself.
