I still use V4 because I still get the results I want with her and I still think she looks good , plus I've invested a lot of money in buying stuff to use on her and I'm not going to stop using her any time soon.

I've used G2 but I don't think she is easy to work with in poser and slows my system down, plus when an outfit doesn't fit her quite right the morphs to fix poke through are generally less, I also don't think in many cases she looks as good as results I can get using V4

I've played around with Daz when G3 came out but I really can't get used to daz and its a huge money sump to transfer over to it and get to a point where I can make renders close to what I can do in poser, also I don't see much difference in look between G2 and G3 so although it means less is now coming for V4 I will make do with what there is and stick with buying from vendors that support her
