hard to compare the two, since they have very different "looks", but...
Meilani
Pluses: nice lean legs, beauty chest, nice olive skin, heart-shape face and sassy look
Minuses: straight hips and flared nostrils (lol - sorry but they are distracting)
Lilith
Pluses: balanced curves throughout, Jane Russell look (face), beauty chest and good hip-waist ratio
Minuses: short and round (but that"s a plus for me), fisting thing is a turn-off
If I HAVE to choose, my vote is on
Lilith cause I'm a sucker for her overall look (fits one of many specific archetypes that turns me on)
