I have played through the latest update but only read and seen the story from afar, plan to play in scrutiny when the big yap yap update arrives! But for my investigation of the 3 female choices we get this rundown of Liz, Amber and Alice
1. From our first introduction to Liz we learn that she literally ignored us until we became 6'8/6'9 (203-206cm) tall and MonsterDickMaXXED. Obviously the only reason she cares about us is that we might be her saving grace for wageslave cash. Its not wrong from her POV and Liz is sexy, understanding of your psyche so its a good choice for us if we were to pursue a deeper relationship. HOWEVER KEEP IN MIND THAT THIS WOULD NOT HAVE HAPPENED IF MC WAS STILL 5'6 AND WIMP DICKED.
2. Amber, I think MC was one of her first BFs which is a bonus but dude Deryl fucked her and lost his virginity to her? If you think in terms of purity and a warriors honor then that girl is lost to the streets. Liz by lore has not been revealed to have sexual partners and quite oppositely only takes a swimming sponsor to alleviate the burden on Amber. Amber, goes fucking and cucking for her personal lust ignoring future consequences (REALLY LOW IQ BEHAVIOUR, OBV THAT LIZ > AMBER).
3. Alice, she only talks to us once we reveal that we are capable as a person. Naturally if we weren't Superhuman (he said the line!) we would have gotten mauled by Michael at the ring and been done for closing off any possibilities with Alice. Now that a relationship can happen, the main determinant in her behavior is our potential and action. She refuses to get us involved unless we agree with her brooklyn bagel mobster family and once we get involved she makes sure to support us thoroughly. She notices Michael is the turbo battle autist so she can't have anything sexual with him. We on the other hand make a good fit for her fathers legacy and helping her or we ourselves keep up the legacy.
Alice' text was more lengthy because of the brooklyn bagel mafia part. Ultimately we what we want to understand is what marriage really entails. Ignore our 1970+ dating era and look deeper into marriage. Marriage is to enter a covenant relationship between a male and a female. Now this has been done for numerous reasons, wealth, status, power, lust etc (e.g queen marrying a 12 year old prince of some kingdom or a king marrying a random hot peasant from the street).
So who would be the best choice? Its clear that we can cut Amber out from the beginning. If you compare her to Liz, she is simply more lacking in every point except that she got nice blue hair ends. What she would provide in terms of a marriage seem to only be lust. Liz, the more mature and cardboard personality girl has the smarts, looks and potentially if she didn't get involved, a good future in both career and well-being. Alice has cash, looks, status, property BUT is a criminal which could damage MC in the longrun depending on his career. Therefor if we base our choice purely on gains, Alice is the best choice. If we base our choice on "morality" then Liz is the better choice (not a criminal duh).
TLDR: ALICE BEST CHOICE BECAUSE SHE OFFERS THE MOST. IF YOU ARE A GOODY TWO SHOES GO CARDBOARD QUEEN LIZ. AMBER IS THE INFERIOR VERSION OF LIZ WITH A PERSONALITY ADDED.
