I like Vicki4 a lot. But since she has 50 thousand morphs built-in ( so she's a massive cr2 file ), she's impractical to use unless you're just doing portraits. 

Vicki 3 has a great face but her shoulders bend weird and her thighs flatten out with kneeling poses.

To pick up the harp again... I wish Vicki 4 came with an injection ready version
