I've spent over $750 on V4 so far and to this point I haven't created one character for her yet that I'd use in one of my projects... I always revert back to V3.  

The new Vicky is just a plain Jane character that's really lacking to this point and really should have been the replacement for S3P instead of Vicky (she's a smaller, younger character with limited morphs just like S3P).  Adding the new muscle morphs helps (although I'm pissed that Daz3D wants us to pay for these morphs that SHOULD have come in the morphs++ package) but she's still missing around 50-75 face morphs that would make her really usable.

I really hate to say it but I also hope Daz3D steals Apollo's scale abilities too so V4 can get the correct body type she should have come with instead of Steffy's.
