I haven't played it, but I intend to get it. I have been watching the "No Mods Shop Class" by Skooled Zone on YouTube. Apparently, each of the DLCs comes with a set of new "standard" workshop items for building your settlements. This by itself is worth getting the DLC for me, as it expands the available inventory for building materials and furniture for fantastic-looking settlements. I don't know what is specifically in that DLC, but you can probably google it.
