I was a Poser user from Poser 3 through Poser 11 and always found the interface very easy to use, so I held off from using Daz Studio for a long time (and was very frustrated with the interface each time I did try it, because it didn't seem intuitive at all).  But  after seeing so many attractive Daz characters, starting with Genesis 3 and even more so with Genesis 8 and 8.1, I became frustrated with the much poorer quality of the figures for Poser and the fact that very few vendors were supporting Poser figures any more, and I  finally started using Daz Studio instead of Poser.  As a result, I didn't upgrade from Poser 11 to Poser 12.  If someone came up with a version of Poser that could use the newer Daz figures natively, without complicated work-arounds, I would be happy to buy it, because I still prefer Poser's interface to Daz Studio's, but I don't think this is very likely.
