Quote - Well, mainly use Reality, gen4 figures (mainly V4 and M4), and I think dfromers and smoothing are the most advanced features I have used. Given that, is there a hige beneift to upgrading?

If you are upgrading from DS4, the main advantage is that smoothing and morph transfer works much better.

The main disadvantage that I personally have is due to my use of scaled characters. Clothes, hairs and shoes don't fit the scaled characters correctly. The issue is fixed but have not been released and as usual with Daz, no communication on when updates will be available.
