I use Poser 12. No reason other than I want the latest greatest. It is still a very good software for what it is intended to do.  I think it is better suited to creators then casual dabblers in digital art. It is better for still portraits than animations, although the latter is still do-able. I do wish the cameras had more functions such as types of lenses. As long as the content created using Poser can be transferred to other software for downstream pipeline, I think it remains a relevant software for its price-performance, and most users in this market segment would be hobbyists. Realistically, though, casual hobbyists can easily obtain some type of results similar to Poser renders, if they use AI art generators, nowadays. So unless the intended use of such images excludes AI-generated art, they will need to use software like Poser to create.
