I am pleased enough with V4 that I am going to convert over entirely - to me it's not a really big change as I've only been obsessed with Poser for a pretty short time and I don't have that much to un-learn anyway.  I've avoided buying much in the way of conforming clothes because generally they are too recognizable for what I want to do, and my assortment of dynamic clothing I'm comfortable with resizing and reshaping to V4.  Some important things have yet to be released, and I'm still annoyed about the name "Full Morphs++", but I have little to lose in moving away from V3 in my situation because I'm such a nub.  

V4 is just tremendously easier to work with for me.  For people just getting started with Poser I'd recommend they just start with V4 and spare themselves some learning curve.
