I use V3 most often, simply because she has so much support. We're awash in a sea of V3 content. No other figure comes close.

My personal favorite is Steph Petite. I like her looks, and she bends and poses better than V3. Especially from the rear. V3's butt tends to explode when you bend her forward. But Steph doesn't have as much stuff as V3.

Laura is an interesting possibility. There are morphs that mature her. Netherworks' are great, and only a few bucks. You can also transfer V3 or SP morphs to her. Her arms look better than V3s and SPs. Her head is large compared to her body, since she's supposed to be a child, but given the typical DAZ pinhead proportions, that's not really a flaw.

V3 RR is another possibility. She can take all V3's textures and clothing, and you don't have to inject the morphs. It is a lower-res mesh, though, and not as realistic for closeups or nudes.
