Dims and Text in model space. I don't care what argument anyone offers. I've done titleblocks in model space, all drafting in paperspace, model in viewport with dims/text in paperspace...by far the easiest for me to use and explain to others is EVERYTHING in model space except titleblock information.
Our previous cad manager botched the use of Annotative dims and text. Once I took some time to make adjustments and put some lisps in acaddoc, my users don't have issues. When done correctly, it's relatively thoughtless.
The people that DO have issues, mostly come from owning their own company and are used to doing it their own way. My response is, "If it's our logo on the drawing, you do it our way."
