I still use V3 more than anything, mainly because I've taken a couple years getting a character that I'm happy with. I can't seem to get to the same place with V4. Not to mention I've spent literally thousands of dollars on clothing and stuff for V3, A3, S3, M3, that I just can't justify leaving V3 behind for V4.

V4's face has been a problem for me, no matter how hard I try I can't get a decent face out of her. The eyes seem to be the main problem. As for her body, I like V3's better, after my morphing, of course. I mainly use Harvey Mann's V3 New Gen 2 with Daz morphs applied as well. Makes for a very resource-heavy figure (though still not as bad as V4). And V3 New Gen 2's body morphs generally work better in apps like Tailor for applying morphs to clothing, since the morphs were all done with magnets. In other words, you don't get nearly as much, if any, clothing distortion with the New Gen 2 morphs transferred to clothing.

Sure, I'm still very bugged by V3's joints (Shoulders, elbows, knees, butt, etc), but overall I can get the figure I want out of her, I haven't been able to so far with V4.
