I too am a convert after using Poser since version 2 and up until PP 2014. I had played with DS ever since it came out and couldn't stand the interface either. What changed things for me was up to date content and the add-ons that I was seeing appear for DS. Pose converters, Measuring tools, hair plugins that were WAY better than Poser's hair room, easier to import homemade models, etc.. Simply put, DS seemed to be the more progressive system, so I persisted and now I use DS 4.8 Pro exclusively. So I'd encourage the OP to just keep trying. I also got a lot of help from the New User area in the DAZ community. So don't be afraid to ask.

One tip: My biggest hurdle was understanding the way the view-port works. You don't get any default cameras or lighting when you open DS like you do in Poser. I couldn't for the life of me get the perspective of my scenes right. Everything looked like I was viewing it in a "fish eye" lens. To make the transition easier and make the view-port more "Poser like" I set up a base scene in Poser ( say with a plain V4) and saved it as a pz3. I then opened it in DS and I got my "poser cameras" and base lights in DS. I deleted V4 and saved what was left as a scene preset ( File Menu-Save as- scene). I also made myself a "floor" out of a large plane primitive. Now when I start a new project, I first load my startup scene and things look a lot more familiar.
