V3, in my opinion, probably has the most market support available.  She's a pretty good figure with the exception of her shoulders.

V4 is an attempt to make a female equivalent of Apollo.  Her shoulders and joints are probably better than any other female figure out there.  There's a bit of oddness with posing and positioning her eyes though.

I wish CP had consolidated all of the G2 Females into one figure and spent a little more time fixing her shoulders.
