You **** the 1st one and forget about her. The 2nd one is more likely wife material. As long as she's good looking, it doesn't matter that there are hotter women out there if she's cool.
This brings up Al_4_State's Hotness-to-Tolerability Ratio. As a woman increases by .25 on the hotness scale (1-10), the odds that she has a massive, irreconcilable character flaw increases by .30. What this means, is that any woman hotter than an 8.5/10 is guaranteed to have a severe character flaw, making her an incompatible long term partner.
