Best Girl? (Patreon)

Work is continuing on the debugging for V1.5.1. I've successfully fixed a few of the more annoying bugs already, and I'm about to start going through run after run to hunt for others. Once that's done, it'll be on to the next small update before tackling the grand finale. And to better help guide my decisions for the last area, I need to know who is the best girl. 

Game spoilers follow:

Who's your waifu of choice of the characters in the game so far? Obviously the wife has the broadest amount of content, but how does Meloni's shy politeness stack up against Lustra's sarcastic sadism and total lack of modesty? Or Olga's robotic helpfulness and total lack of nuance? Or Helga's helplessness after her tragic fate?

Or just who has the plain sexiest scenes?

What I want to know is, put in a line-up, which of these girls would you choose to get busy with?
